In case you are working with environments or docker images you can really change  etc host I recommend just changing the binding from star to 0 0 0 0   So  basing on my case for instance  instead of   -agentlib jdwp transport dt socket server y suspend n address   5005    You would define it as   -agentlib jdwp transport dt socket server y suspend n address 0 0 0 0 5005

This error typically comes up when the necessary port is taken by another program   You said that you have changed the HTTP connector port from 8080 to 8081 so the two Tomcats do not clash  but have you also changed the  lt Server port       in tomcat conf server xml to be different between your Tomcats   Are there any other connectors ports which may possibly clash

Check whether your config string is okay   Xrunjdwp transport dt socket server y suspend n address 9999   I just had this issue today  and in my case it was because there was an invisible character in the jpda config parameter    To be precise  I had dos line endings in my setenv sh file on tomcat  causing a carriage-return character right after  dt socket

This error mostly comes when we forcefully kill the weblogic server   kill -9 process id    so before restart kindly check all the ports status which weblogic using e g  http port   DEBUG PORT etc by using this command to see which whether this port is active or not   netstat    an   grep   Admin  7001 or something  Managed server- 7002  7003 etc  eg  netstat    an   grep 7001  If it returns value then  option 1  wait for some time  so that background process can release the port option 2  execute stopweblogic sh Option 3  Bounce the server host or restart the system   My issue was resolved by option 2
