Hi Support I using pgagent over 2 years. There are over 30 jobs running by pgagent. Recently. I found a problem that sometime the pgagent hang by unknow reasons. From the stack information. Look like the pagent experience dead-lock issue in code. The stack display many thread stop on this function “in __lll_lock_wait” If you need more information. Please let me know. I suspect this is a bug.
I collect to pgagent trace log and stack information on the attachment. pgagent trace log pg_agent_11_24.log pg_agent_11_26.log pgagent process stack others information. version: pgagent_10-3.4.0-10.rhel6.x86_64 PG 10.5 The typical stack information.
