Confluence 6.6.9 Thread Limit

[David Urquhart]

We have just upgraded to Confluence 6.6.9 and are getting Thread Limit messages

os is Linux

I edited /etc/security/limit.conf and added,

conflu      soft   nofile  4096
conflu      hard   nofile  8192
conflu      soft   nproc   4096        
conflu      hard   nproc   8192

conflu is our confluence user.

I then restarted confluence but still get the Thread Limit health check warning

What's going on ?

Thanks

HI @David Urquhart

Please Reboot your machine and test the new limits configuration

Thanks

Just noticed "systemd ignores system ulimits. The values will need to be specified in the proper service file <servicename>.service. A list of values can be found here."

we have confluence running under systemd, so which values do we need to set

Changed

LimitNOFILE=4096
LimitNPROC=4096

in confluence.service file, okay now

do you have to reboot machine after editing /etc/security/limits.conf ?

We have not done so.
