Hi list, haproxy is segfaulting multiple times these days for no apparent reason. At first i thought is was a load issue but even few RPS made it crash.
Symptoms are always the same : segfault of a worker then spawn of a new. If load is very high, spawned worker segfault immediatly. In the messages log, the offset is always the same (+1e2000). I'm running 1.9.4 (from vincent bernat package) in Debian stretch. In haproxy logs : Feb 12 11:36:54 ns3089939 haproxy[32688]: [ALERT] 042/113654 (32688) : Current worker #1 (32689) exited with code 139 (Segmentation fault) Feb 12 11:36:54 ns3089939 haproxy[32688]: [ALERT] 042/113654 (32688) : exit-on-failure: killing every workers with SIGTERM Feb 12 11:36:54 ns3089939 haproxy[32688]: [WARNING] 042/113654 (32688) : All workers exited.

How could I diagnose further without impacting production too much ? Thanks, mildis
