Hi all, I encountered an unintentional process abort with SIGSEGV when a Java process received a SIGUSR2.
I was little surprised because I believed that the SIGUSR2 was to be ignored when it had no user definition. Is there any documentation for the behavior? # # A fatal error has been detected by the Java Runtime Environment: # # SIGSEGV (0xb) at pc=0x00007fca804a40a2, pid=2137, tid=0x00007fca81949740 # # JRE version: OpenJDK Runtime Environment (8.0_121-b13) (build 1.8.0_121-b13) # Java VM: OpenJDK 64-Bit Server VM (25.121-b13 mixed mode linux-amd64 compressed oops) # Problematic frame: # V [libjvm.so+0x8700a2] # # Core dump written.
