The default isolation level in MySQL InnoDB tables prevents a process
from seeing ANY changes made since the last commit in this process.
That means that if your mod_perl process has been sitting around waiting
for requests for half an hour, it can't see anything that has happened
during that time until you issue a commit in that process.  The fix is
to switch to a more reasonable isolation level.

I wrote this problem up here:
