Robot Crash

I have also  been experiencing crashes but the trace shows that it is running 
out of memory unlike Guy's problem. I have a large amount of physical memory 
512M and have bumped the stack limit to 32M. The program runs longer but still 
keeps growing until the out of memory. I am trying to use the program to test 
firewall filter loading by running as many fetches as possible for a few 

The problem that I see in the stack trace is a huge number of HTMIME_free 
calls all in sequence. This sounds like a recursive call that gets out of 

For these test I am running a simple command such as :

  webbot -depth 4 -prefix [uri] [uri]
which points at my local server which has lots of pages.

Does the robot/www-lib cache each page and never free it? I have tried the 
runs with an explicit -cache command but no difference.
