We have one annoying issue with openfire. We use Openfire with AD auth and external MariaDB 5.5.41 database, using custom certificate, only TLS.
First, we are trying 3.9.3 with bundled java on windows server 2012 r2 standart (it’s VM with 1 vCpu, 1024 mb RAM), and after 1 day or less openfire service show constant 100% CPU Usage, only helps stop|start service. We are trying update jre version to latest 7u76, but it is not helps.
Second, we are install Openfire 3.10 RC on centos7.1 (Linux openfire.local 3.10.0-229.1.2.el7.x86_64 #1 SMP Fri Mar 27 03:04:26 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux) with bundled jre, we have expirience teh same issue - constant 100% cpu usage. Increasing Java Heap upto 384 mb doesn’t help.
