Describe the Bug

We encounter an siginfo: si_signo: 11 (SIGSEGV), si_code: 2 (SEGV_ACCERR) issue in our puppet server jvm with 2 C lib functions :

  • [libc.so.6+0xb8b0f] __memmove_evex_unaligned_erms+0xaf
  • [libcrypt.so.1+0x25ab]
#
# A fatal error has been detected by the Java Runtime Environment:
#
#  SIGSEGV (0xb) at pc=0x00007f62fc9acb1e, pid=1320745, tid=0x00007f6221597700
#
# JRE version: OpenJDK Runtime Environment (8.0_432-b06) (build 1.8.0_432-b06)
# Java VM: OpenJDK 64-Bit Server VM (25.432-b06 mixed mode linux-amd64 compressed oops)
# Problematic frame:
# C  [libc.so.6+0xb8b1e]  __memmove_evex_unaligned_erms+0xbe
#
# Failed to write core dump. Core dumps have been disabled. To enable core dumping, try "ulimit -c unlimited" before starting Java again

The problem appeared after a constant load of puppet agent request and we have 974 hosts managed by this puppet server.

Steps to Reproduce

We succeeded to reproduce this issue on a sandbox environment (same OS and config), with :

  • 1 puppet server
  • 3 VM instances -> running a script allowing to make puppet agent -t 300 times, in parallel with a sleep of 7 second between every new puppet agent -t

And after 30-40 minutes, the JVM crash with the SIGSEGV issue, either on libcrypt.so.1 or on libc.so.6.

Environment versions

  • puppet agent : 7.34.0
  • puppet server : 7.17.3
  • OS : Red Hat Enterprise Linux 8.10
  • /lib64/libcrypt.so.1 -> libcrypt.so.1.1.0
  • /lib64/libc.so.6 -> libc-2.28.so
  • openjdk : 1.8.0_432-b06
