Application Crashes With Internal Error In The NET Runtime

Question

We have an application written against  NET 4 0 which over the weekend crashed  putting the following message into the event log      Application  PnrRetrieverService exe   Framework Version  v4 0 30319   Description  The process was terminated due to an internal error in   the  NET Runtime at IP 791F9AAA  79140000  with exit code 80131506    This is on a Windows Server 2003 R2 Standard Edition box   Googling this error hasn t turned up anything pertinent   For example  this isn t occurring in VS Studio  but instead on a production box  when the service was eventually restarted  it experienced no further problems   How does one go about diagnosing a bug in the  NET Runtime

After years of wrestling with this issue in a number of applications, it appears that Microsoft has finally accepted it as a bug in .NET 4 CLR that causes this to occur. http://support.microsoft.com/kb/2640103.

I had previously been "fixing" it by forcing the garbage collector to run in server mode (gcServer enabled="true" in app.config) as described in the Microsoft article linked to by Think Before Coding. This in essence forces all threads in the application to pause during the collection removing the possibility of other threads accessing the memory being manipulated by the GC. I am happy to find that my years of searching in vain for a "bug" in my code or other 3rd party unmanaged libraries were only fruitless because the bug lay in Microsoft's code, not mine.

In my case this exception was occured when disk space was over and  NET can t allocate memory in Windows Virtual Memory   In event log I saw this error   Application popup  Windows - Virtual Memory Minimum Too Low   Your system is low on virtual memory  Windows is increasing the size of your virtual memory paging file  During this process  memory requests for some applications may be denied   And previous error   The C  disk is at or near capacity   You may need to delete some files

with exit code 80131506   That s a nasty one  ExecutionEngineException   Starting with  NET 4 0  this exception immediately terminates the program   The generic cause is corruption of the state of the garbage collected heap   Which in turn is invariably caused by unmanaged code   The exact location in code at which this exception is raised isn t helpful  the corruption usually occurred well before the damage is detected   Finding the exact cause for this is going to be difficult   Review any unmanaged code your service might be using   Suspect environmental problems if there is no obvious candidate  misbehaving malware scanners are notorious   If it repeats very poorly then suspect hardware problems like soft RAM errors

A bug in the concurrent implementation of the Garbage Collection on x64  Net 4 can cause this as stated in the following microsoft KB entry   ExecutionEngineException occurs during Garbage Collection   You should first make a deep minidump exploration to be sure that the problem occured during a Garbage collection   The minidump location can usually be found in a Windows Error Reporting entry in the event log following the crash entry  Then  have fun with WinDbg    The latest documentation on the use of the  lt gcConcurrent  gt  configuration element  to disable concurrent or  in  NET 4 and later  background garbage collection  can be found here

I ve experienced  internal errors  in the  NET runtime that turned out to be caused by bugs in my code  don t think that just because it was an  internal error  in the  NET runtime that there isn t a bug in your code as the root cause  Always always always blame your own code before you blame someone else s   Hopefully you have logging and exception stack trace information to point you where to start looking  or that you can repeat the state of the system before the crash

This might be an exception occurring in the finalizer  If you are doing the Pattern of  Class    Dispose false     check what are you disposing as an un-managed resource  Just put a try  catch there and you should be fine   We found the issue as we had this mysterious failure with no logs We did the usual recommended pattern of using a  void Dispose bool disposing     Looking at the answers on this question about the finalizer we found a possible place where the Disposal of the unmanaged resources could throw an exception   It turns out somewhere we did not dispose the object properly thus the finalizer took over the diposal of unmanaged resources thus behold an exception occurred    In this case was using the Kafka Rest API to clean up the client from Kafka  Seems that it did threw exception at some point then this issue occurred

Every 5-10 minutes my application pool kept crashing with this exit code  I do not want to ruin your trust of the Garbage Collector  but the following solution worked for me   I added a Job that calls GC GetTotalMemory true  every minute   I suppose that  for some reason  the GC is not automatically inspecting the memory often enough for the high number of disposable objects that I use

Had the same exact error on WinXP box with latest build of my  NET 4 code   Checked previous builds - now they crash too   Ok  so it s not me      No suggestions here above helped   Much more recent  2018-05-09  report of the same problem  Application Crash with exit code 80131506      A  We were receiving a similar error  but we believe ours was caused by the Citrix memory optimizer    The resolution was to force a regeneration of the  Net core libraries on the host s  where the issue was occurring    C  Windows Microsoft NET Framework64 v4 0 30319 ngen exe update  force   Root cause is still unknown  machine is not being updated and has little use   but that did it for me

I never figured out why this was happening for me  It was consistently reproducible for one of my applications  but went away after simply rebooting   I am running Windows 2004 Build 19582 1001  Insider Preview  with  net-4 8 and I also would not be surprised if this were due to something like a hardware memory error  Also  my application does load some unmanaged code and initialize it  so I can   t prove that the crash didn   t come from that

In my case the problem was related  to  Referencing  NET standard library in classic asp net projects  and these two issues  https   github com dotnet standard issues 873  https   github com App-vNext Polly issues 628  and downgrading to Polly v6 was enough to workaround it

In my case the problem was a C   CLI library in which there was a call to the NtQuerySystemInformation  for some kind of reason sometimes  and under mysterious circumstances   when it was called the CLR heap got corrupted and the application crashed   I ve resolved the problem using a  custom heap  created with HeapCreate and allocating there the buffers used by that function

In my case the issue was due to duplicate binding redirects in my web config  More info here   I assume it was because of NuGet modifying the binding redirects  but for example it was looking like this      lt dependentAssembly gt       lt assemblyIdentity name  Lucene Net  publicKeyToken  85089178b9ac3181   gt       lt bindingRedirect oldVersion  0 0 0 0-2 9 4 0  newVersion  3 0 3 0   gt     lt  dependentAssembly gt     lt dependentAssembly gt       lt assemblyIdentity name  Newtonsoft Json  publicKeyToken  30ad4fe6b2a6aeed   gt       lt bindingRedirect oldVersion  0 0 0 0-11 0 0 0  newVersion  11 0 0 0   gt     lt  dependentAssembly gt     lt dependentAssembly gt       lt assemblyIdentity name  System Net Http  publicKeyToken  b03f5f7f11d50a3a  culture  neutral   gt       lt bindingRedirect oldVersion  0 0 0 0-4 2 0 0  newVersion  4 0 0 0   gt     lt  dependentAssembly gt     lt dependentAssembly gt       lt assemblyIdentity name  Lucene Net  publicKeyToken  85089178b9ac3181   gt       lt bindingRedirect oldVersion  0 0 0 0-2 9 4 0  newVersion  3 0 3 0   gt     lt  dependentAssembly gt     lt dependentAssembly gt       lt assemblyIdentity name  Newtonsoft Json  publicKeyToken  30ad4fe6b2a6aeed   gt       lt bindingRedirect oldVersion  0 0 0 0-11 0 0 0  newVersion  11 0 0 0   gt     lt  dependentAssembly gt     lt dependentAssembly gt       lt assemblyIdentity name  System Net Http  publicKeyToken  b03f5f7f11d50a3a  culture  neutral   gt       lt bindingRedirect oldVersion  0 0 0 0-4 2 0 0  newVersion  4 0 0 0   gt     lt  dependentAssembly gt    Removing all the duplicates solved the problem
