Hi All,
Need expert advices on this issue.
We have Tomcat and Apache installed in our production environment since 5/6
years. Everything was going fine until we started getting application not
responding status from users, upon checking we found out that there was a
MaxRequest error as below,
* In Apache log we have found this error.
[Tue Sep 20 10:48:08.134955 2022] [mpm_event:error] [pid 23940:tid
140413844547328] AH00484: server reached MaxRequestWorkers setting, consider
raising the MaxRequestWorkers setting
* we have seen the below error on tomcat logs
[cid:image001.png@01D8D2AF.EB134CD0]
We increased 16gb memory on both servers , now we have 32 Gb memory in each
servers. But the issue still is there. Suddenly we start getting the error and
we have to restart Tomcat and Apache.
FAQ:
1. Need permeant Solution on this as restarting the instances has became too
frequent these days.
2. We increased MaxRequestWorker value 400 from 200.
<IfModule mpm_worker_module>
StartServers 3
MinSpareThreads 75
MaxSpareThreads 250
ThreadsPerChild 25
MaxRequestWorkers 400
MaxConnectionsPerChild 0
</IfModule>
1. Database and network team reported no unusual activity during the issue.
2. Code is refreshed every month , no issue found on coding side.
3. While the issue starts the server becomes low on memory.
Thanks and Regards,
Koustav Naha
