Did this one get resolved?  I can't find the solution.

Seems to be a pipe control issue of some sort.  The httpd process that 
starts the 'echo $string | /usr/locla/bin/ispell ' starts growing 
uncontrollably, (in my case it has eaten up close to 1.5GB before I've 
killed it).  After 'kill -9'ing the httpd process, the associate ispell 
process starts taking up the CPU, when trussing it, you can see that it's 
trying to write to the pipe, and is receiving a SIGPIPE, and looping 
uncontrollably.  Then, after a 'kill' on the ispell process, httpd takes 
it's turn at sucking up the CPU cycles.  After you kill on that httpd 
process, you're happy again, until next time.
I lost my truss data, but I can send it on next time it happens.
