Hi Dave Thanks for your quick response. This env was deploy on Jan 2019 by my team mate. Currently the pgagent have 30 jobs running. The version is pgagent_10-3.4.0 I don’t know how to upgrade the pgagent. I try to find upgrade document. But failed. Only find that edb ppas could upgrade pgagent. https://www.enterprisedb.com/edb-docs/d/edb-postgres-advanced-server/installation-getting-started/upgrade-guide/11/EDB_Postgres_Advanced_Server_Upgrade_Guide.1.13.html
If I re-install the pgagent with latest version. Whether the old pgagent jobs will drop with old version pgagent ? Would you like to guide me to make pgagent using new Boost package and no impact currently working pgagent jobs ? I don’t want to rebuild all pgagent jobs. Thanks in advance. 徐志宇（Jack） Database Engineer DB Team,ITS.

Please upgrade and try again. Thanks. On Thu, Nov 26, 2020 at 8:05 AM Zhiyu ZY13 Xu <xuz...@lenovo.com<mailto:xuz...@lenovo.com>> wrote: 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.
