sigsegv fault on libc occured in puppetserver jvm

[alexandreleclercqdecat]

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]

#

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
