Ubuntu OpenFire stops working and I must restart computer

After running OpenFire on my ubuntu desktop for a while it eventually stops working and I have to restart the whole computer to get it working again.

I am using port forwarding but the ports are forwarded just fine. It also seems like all of my hosting services, ie: apache and mysql, fail as well.

I get errors, “Server not found.” when I try to connect to the control panel.



are you using a physical server or a virtual one?


Does the other services only crash if you run Openfire?

If you have a virtual server, does your server clock work correct? It’s a very complicated thing to let a virtual clock run correctly, if the CPU speed changes all the time corresponding to on the CPU load. If you just sync the time every hour or so using ntpdate and the time jump is larger than a few seconds network programms (like Openfire, Apache, MySQL, …) could crash.

When having clock problems and using VMware, here are some useful links:

I am running the server here in my home.

Well I am not sure, they all start up together.

I think it may now not even work after I restart… I will check and see though.


did you set high Xmx values for Openfire? Maybe your server/desktop runs out of physical memory and starts to page things in and out - this makes every server very slow.

You may want to take a look at your used memory with cat /proc/meminfo". Take a look at http://www.redhat.com/advice/tips/meminfo.html for the meaning of the output, “MemFree” is usually low as Linux uses memory as a read-in cache (Cached). When “Cached” gets very low you may get problems.
