Re: 5.8.10 RELP server exhausting connections and stops responding
[In reply to]
|

Im still having this issue on my end, no luck resolving it here even
after upgrading to 5.8.13 . I have a similar config to the below except
I increase some of the queue timeouts. What I have found is that on my
server the issue takes about 2 days on average to show up after an
rsyslog service restart on the server.
After restarting the service, my rsyslog responds to RELP normally and
running 'netstat -alnpt | grep rsyslogd | wc -l' my server averages
about 200-250 connections. After about 2 days the rsyslog cpu usage will
spike to 100%, the number of open TCP connections will be around 800 and
it will not respond to RELP connections.
Ive tried adding '$ActionSendTCPRebindInterval 25' to client/server
sides to see if rebinding would help but it didnt.
Ive resorted to restarting my server service daily as I cant figure out
what else to do.
