The server ran out of disk space and we had to do some emergency cleanups.

Down since: Unsure, estimated to be +- 09:00 CDT
Service restored: 10:30 CDT

I believe my problems (described here) were caused by low disk space. Today, for example, everything seems to be fine. Thank you!

I don't think this was the reason.
As I said, it happens to me almost every day when there is a high answering activity.

Hmmmm ... I think I have an explanation for your situation: you have entered the Michel mutating error. As you've mentioned "when there is a high answering activity", it means that YOU cause problems for yourself. I don't have that kind of statistics (average number of messages per day), but I bet you are the leader on that list.

So - if you want to avoid such problems - don't burden the server that much and everything will be just fine.

I'm sure this is a separate problem. Please mail/ PM the details to me whenever it happens.

Was there a disk space problem again today on 19-Jul around 8:00AM GMT - 5 ?

The site seemed to be very slow and sluggish.

Just curious.

Nope. The symptom for out of disk space is complete site failure (MySQL cannot establish connections).

BTW: We've put some monitoring scripts in place, so, I doubt if it will happen anytime soon again.

It just happened again. The component causing these problems will be upgraded over the weekend.

I cannot access this site almost every day at 3 PM Bangladesh Time.
I don't think that it is disk space problem because it is happening every day.

What was causing them? Could you say a word or two about the problem and its solution, please?

We had two problems:

1) PHP was logging excessive notice messages. This caused logrotate to use a lot of CPU resources. The solution was to identify the programs logging messages and upgrade them or fix them manually.

2) Databases were getting too busy. The solution was to instigate more aggressive caching. For example, the wiki is now serving from a file system cache.
