Site performance, Server errors, outages and tunings - Strappado - 18 Jan 2011
I am getting this a lot since yesterday. Trying the same addres again often works. I remember having read something about database troubles, but couldn't find it, so I wrote it here.

Capacity problem. As I said I will probably have to upgrade to the business model, but that will require some investments. See here: http://www.likera.com/blog/wp/archives/8836

Also we've reached another record today: 62 online users.
Testing new environment after the upgrade - Like Ra - 20 Jan 2011
The site is running on a virtual server now. But after some time we are getting server error again. For some reason PHP processes get stuck. After reboot or after I manually kill the stuck processes, everything is back to normal.
I suspect one plugin I've currently disabled. Let's see if it gets better.
RE: server error, address not available - Like Ra - 21 Jan 2011
apparently it was the caching one w3-cache. Instead of increasing performance it hogged it. Took me quite a while to figure out what it was.
Let's try to reinstall it...
RE: server error, address not available - Like Ra - 21 Jan 2011
Reinstalled, reconfigured, crashed again.
Removed...
Fun, fun ...
RE: server error, address not available - Like Ra - 21 Jan 2011
Too many stuck PHP processes ... Does not look good. This is exactly what brings the system to a halt.
RE: server error, address not available - Like Ra - 21 Jan 2011
Still works... Meanwhile fixed another old error.
RE: server error, address not available - Like Ra - 21 Jan 2011
No, there is something else...
RE: server error, address not available - Like Ra - 21 Jan 2011
I don't get it ... I see no problems at all, but 15 min ago the load was 61!
top - 18:08:01 up 1:17, 2 users, load average: 46.63, 61.28, 41.59
So I had to reboot the VPS (again).
