After 511 days of uptime, I decided it was time to bite the bullet and do a version upgrade. The `do-release-upgrade` command did what it said on the tin, and the upgrade from 9.10 to 10.04LTS was pretty straightforward (some downtime waiting for the disk to fsck, and requiring ops to manually reset). Unfortunately, the upgrade made WordPress pretty unhappy. Some combination of WP, APC, and potentially WP Super Cache? Instead of using Ubuntu’s APC (3.1.3p1-2) I switched to a pecl install (3.1.9). This didn’t solve things, so I bumped up the apc.shm_size to 128M…

I’ve been lackadaisical lately w/ my sysadmining, but with the unfriendly waters, I took some time to tighten the ship up a bit. I probably be publishing a little “hardening Ubuntu for really lazy/busy devs” guide soon.
