Hi All, We are facing issues on tomcat. Core dump file generating very frequent twice to thrice in a month and core file size would be 13GB to 15GB every time .Whenever this issue is happening tomcat services stopped automatically. We have done analysis of hs_err_pid.log file and based on analysis we have tried many thing (such increased tomcat heap memory ) but unable to resolve this issue. Please suggest.
There's not much to suggest: A core dump can be analyzed for the root cause of it being generated. Typically a problem that goes beyond what Java code itself is capable to do. More often than not, native code - if there is any involved - would be my first place to look at. Also, as the JVM is native code itself: Make sure that it's up-to-date. On top of that: Yes, when a core dump is generated, the process for which it was generated is indeed stopped. That's what a crash does to your process (even if core dumps were disabled or went to /dev/null). You might want to set up your systems for automatic restart, most likely with alerting someone of the condition and the restart, so that you have an overview over how often it happens, but generally keep the service up.
