how to debug SIGSEGV in jvm GCTaskThread

Question

My application is experiencing cashes in production. The crash dump indicates a SIGSEGV has occurred in GCTaskThread

It uses JNI, so there might be some source for m

Answer 1

Since the faulty thread seems to be GCTaskThread, did you try enabling verbose:gc and analyzing the output (preferably using a graphical tool like samurai, etc.)? Are you able to isolate a specific lib after examining the hs_err file?

Also, can you please provide more information on what causes the issue and if it is easily reproducible?
