server reached MaxRequestWorkers setting

[Nico n]

Hello,

on my server I host Jira and Confluence, both behind Apache Web server v.2.4.6.

At one time, I can't reach both applications, so i found out in Apache error.log:

server reached MaxRequestWorkers setting, consider raising the MaxRequestWorkers setting

I didn't tune Apache, because before I would like to understand what means this error relating Jira and/or confluence. Somebody could help me ?

thanks in advance

Nico

This is not a Jira or Confluence error in general, unless they've got something going wrong internally (which would have given you other symptoms).  This is usually a problem when you have an external process making many, frequent calls to the services from the outside.

Have a look at the apache access log - is it showing lots of hits?

Thanks Nic, I have looked to apache logs (access.log and ssl_access.log but I don't have lots of hits). Besides, with this command 

netstat -an | egrep ':80|:443' | grep ESTABLISHED | awk '{print $5}' | grep -o -E "([0-9]{1,3}[\.]){3}[0-9]{1,3}" | sort -n | uniq -c | sort -nr

i have checked number of established connections grouped by ip. I didn't find lots of connections. In fact, the interruption of the service occurred "only" 2 times in 6 months. 

I was guessing that could be a problem with Jira because of this knowing issue https://jira.atlassian.com/browse/JSDSERVER-3492 that I got at the same time of the system interruption.

Anyway I have JSD 3.2.3, where this issue should be solved.

thanks again
