I wonder if this has anything to do with the fact that the Moin site has been very slow this weekend, and throwing frequent errors when trying to edit pages. In the end it worked, but it felt like something wasn't quite happy in there.
And ssh-ing directly into the machine is also *very* slow right now. A quick top shows:
top - 01:27:36 up 126 days, 7:59, 2 users, load average: 20.11, 14.59, 12.91
Tasks: 165 total, 4 running, 161 sleeping, 0 stopped, 0 zombie
Cpu(s): 33.1% us, 4.1% sy, 0.8% ni, 0.2% id, 61.0% wa, 0.2% hi, 0.7% si
Mem: 2075100k total, 2020196k used, 54904k free, 15040k buffers
Swap: 4192944k total, 1201472k used, 2991472k free, 232596k cached
That's kind of a high load... And I see several python and trac.cgi processes eating up quite a bit of cpu.
Cheers,
