There may be a memory leak in the Wordpress appliance.
I downloaded the ISO and installed it to a VPS running on top of a host running CentOS 5.5 KVM.
After turning the site live, everything works fine for a while and then the console shows the kernel is killing processes because the system has run out of memory. The VPS has 512 MB of RAM allocated to it. From the webmin usage info, the usage stays at about 300MB for a long time after the appliance is turned on.
This keeps happening so it seems to be a systemic problem. We tried turning off all plugins to ensure it is not something in the blog and the appliance still locks up.
Since this is a production system, we are moving it to a CentOS based Wordpress install. If that is stable, I would highly suspect the TKL appliance has some underlying problem.
Has anyone encountered a similar situation?
Any ideas how to diagnose where the problem could be?
