I pull up this issue.
The error occurs again since two weeks.
Today, forums alternate between error 1040 and being slower than a snail.
It is not possible to access them right now.
I think you have some fast snails in your area :-)
At least the vm itself seems relative ok now.
However, I can see that there has been mysql problems earlier, seems to be
the old problem, that httpd tries to grap more connections than available.
This time I could also see that the mysql buffer spaces had been pretty
full, without knowing the forum software, I would say that some of the
tables should be converted to innodb. We did that on mwiki, and that change
alone allowed mysql to handle a lot more parallel select statements (60-70%
of the total).
In general the configs are ok for normal daily traffic but cannot handle
peak situations.

For interested look at:
INFRA-6097 which request mysql optimization and
INFRA-6098 which request httpd/ats/php optimization
They are assigned to me, but when I do it, I need somebody to help
test...any volunteers ?
Just before one outage of the forum today there were 150 users online, which is
a long way short of the maximum logged of 294. An interesting thing I have
noted is that it is often slow, leading to an error 10040 at about 0930 UTC+1;
this happens quite regularly.
Maybe this is the backup. Bugzilla has the same behavure at the same
time. Or ASF Server simply don't like morning ;-)
