pvestatd crashes with "free unreferenced scalar" segfault after fork #49
Description
pvestatd crashes with memory corruption errors when using the TrueNAS plugin:
pvestatd[13258]: Attempt to free unreferenced scalar: SV 0x5e4c0562da98
kernel: pvestatd[13258]: segfault at 269c7b008 ... code=killed, status=11/SEGV
Root Cause:
Persistent WebSocket connections stored in %_ws_connections are inherited by forked pvestatd child processes. Both parent and child have references to the same IO::Socket::SSL objects, causing Perl's reference counting to corrupt when either process garbage collects.
