[sr-dev] Re: [kamailio/kamailio] ndb_reids module in event_route[tcp:closed] route block error: "no redis context for server" (Issue #3768)

26 Feb 2024


      Kamailio version 5.4.8 can be used normally. I have checked the logs and found that each process successfully initialized the variable, and no other errors were found. I also did not see any other normal business processes that set rsrv ->ctxRedis=NULL. All processes are only released when the program exits. Also, I saw from netstat that all TCP links are in an established state.
