Comment 48 for bug 105457

I woke up this morning and found I was experiencing this issue on 9.04 (final, standard desktop version). I also saw two instances of mysql_safe with one eating all the CPU. I installed mytop but didn't see anything happening, and /etc/init.d/mysql restart did not help. Both mysql.log and mysql.err were empty files.

The only mysql database on this box is for Amarok 1.4, and amarok was not running at the time. Last night the problem was definitely not occurring, and I hadn't logged into this system for a couple days prior to that (the box was restarted on Sunday). The commands I performed last night were:
an apt-get update
apt-get upgrade
apt-get install prelink
prelink -amR

I just went through y dpkg.log, and mysql was updated last night, so I'm willing to bet the bug was somehow triggered by that process.
