Wildfly24.0.1.Final domain instance hang Issue

[Mohammed Alam]

Dear Team,

We are facing instance hang issue . As per our analysis we have setup doamin wildfly 2 hosts with 4 instance every week its instances going into hung state its required restart but after restart its working fine but us its production we cant resatrt every week. Please find below configuration details of our domain wildfly and screenshots during hung state.

Screenshots of the console are not sufficiently informative to diagnose the cause of a hung process.

Rather, you should perform a thread dump of the hung JVM process (e.g. kill -3 <pid>), attach any suspicious stack traces and provide the necessary context for these traces (and perhaps attach relevant source code) so that someone with zero knowledge of your application could possibly help.

Your GC log is not relevant to diagnosing a hung process.  Please see my previous post.
