We lost one of our Swiki servers last month - it just kept crashing more and
more often, and we couldn't figure out why. We eventually simply took it
off-line, and moved our necessary Swikis from that machine to another server.
Now, our main Swiki server, swiki.cc.gatech.edu, is crashing a couple times a
day. Below are some notes that our tech support folks just sent me.
Has anyone seen anything like this? Any suggestions for debugging or even
fixing?
Thanks!

I had to restart the swiki.cc server software twice
today. I searched for large XML files and they all seem to be less
than 10KB.
I did not find a debug.log file...just a LowSpaceDebug.log file.
Also, one symptom is that when the server is doing fine...the swiki.cc
squeak process seems to eat about 20% or less of the cpu. But, when
it gets hosed it takes 100% cpu. I used strace and it's spinning on
gettimeofday calls...but they are very slow....
...
gettimeofday({1223328462, 522789}, NULL) = 0
gettimeofday({1223328462, 522876}, NULL) = 0
gettimeofday({1223328462, 522936}, NULL) = 0
gettimeofday({1223328462, 522991}, NULL) = 0
...
When I do the same strace call on coweb.cc, it's doing the same
gettimeofday calls but much, much more quickly.
