I've already sent a support ticket, but he (Lee) told me to give a look at the community, because he said to me "on our end looks to be functioning normally".

My problem is that since (about!) 14:00 of today, my forum is working sluggishly. I don't understand why ... I've not changed the configurations or added new softwares, daemons and so on. Nothing.

Usually (it happens only today) it becomes slower when I try to reply/read a single topic, but it's not a rule. When I try to load the unread posts it's fast, while it should be slower - since it's a more complex query. I don't know what the problem could be.

This is the MTR output:

Btw: he told me about an OOM problem, but as I've stated: I've not changed anything. The number of connected users is always the same (a range between ~70 and ~150).

Please, can you help me?

It's working fine now.

Bha....

kernel OOMing is strange thing and it doesnt care that if you changed any thing at all! It just happens get in to newest kernel to see it if helps!

Did you update any software? Even if you haven't added new software, newer versions of existing software sometimes have unexpected glitches.
