Confluence 6.6.9 Thread Limit

David Urquhart_hz0u45

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

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

We have not done so.

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

David Urquhart_hz0u45

Changed

LimitNOFILE=4096
LimitNPROC=4096

in confluence.service file, okay now
