[ic] IC gone wild ?

[DB]

I'm running 5.6.1 on a fairly beefy Centos 5.3 server. I have about
650,000 items in a Mysql database. Things run very smoothly for the most
part.

Yesterday I began getting complaints from employees and customers about
the site acting funny... they tell of seeing a blank "white screen"
appearing after attempting to search for an item, add an item to the
cart etc.

Finally I noticed that my main IC (not catalog) error log was quite
large. It was not getting rotated (my fault or course) and had grown to
131MB. In the log were thousands of lines like:

- - - [22/August/2009:08:19:06 -0400] - - page server pid 25756 won't die!
- - - [22/August/2009:08:19:08 -0400] - - Spawning 5 page servers to
reach 5 StartServers
- - - [22/August/2009:08:19:08 -0400] - - page server pid 25762 won't die!
- - - [22/August/2009:08:19:08 -0400] - - page server pid 25761 won't die!
- - - [22/August/2009:08:19:10 -0400] - - Spawning 5 page servers to
reach 5 StartServers
- - - [22/August/2009:08:19:10 -0400] - - page server pid 25768 won't die!

Rotating the log and restarting IC seems to have cured things, but I'm
wondering what caused this. Is it possible that the large size of the
error log was to blame? Any thoughts are welcomed.
