JVM Crash due to SIGSEGV

Question

Our server hung because of a SIGSEGV fault..

A fatal error has been detected by the Java Runtime Environment:

  SIGSEGV (0xb) at pc=0x00007ff5c7195aa         


        

Answer 1

It is telling you that an error occurred in code loaded from libdtagentcore.so. More specifically it happened in function named restrict and at offset 0x506f6. The first offset mentioned (0xb7aaa) is offset within the library itself. If it was build with debugging symbols (-g) you can look at the code that caused the exception, on Linux something along the lines of:

addr2line -e libdtagentcore.so -C -f 0xb7aaa
