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 _______________________________________________ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l

Hello Travis,

If you're running any older 1.2 release, go upgrade to 1.2.6 or so. Of course, you can just restart memcached and wait for it to happen again :)
