Hi,
We're having some intermittent problems with memecached, and thought someone
might have a suggestion for us.
We have a single memcached server using 2GB of the 4GB of system memory.
Lately we've been occasionally seeing on the site <mediawiki_messge_key>
instead of the contents of the message. I'm running mctest.php a few times
from each of our Apache servers, and the 'get' returned is occasionally 0,
but I can't seem to reproduce this problem reliably. The load on the server
running memcached is very low, and the number of connections to the
memcached server fall usually between 5 and 15, and we have 6 Apache
servers.
Could we need more memory, or could it be a network issue? Does memcached
have any commands to tell how much of the allocated memory it is using, or
are there any other diagnostics I can run to shed light on the issue?
Thanks.
Travis
