You got a segfault already with 'recycle?
Is it always 3-4 hours that it crashes or
is that an average?
(Does adding 'recycle decrease the time?)

You're probably right. (but you could be wrong - perhaps the
server doesn't always return the full page, possibly causing
a problem? or returns too much data occasionally...)
I've been running your script for ~2 hours now on win2k.
No segfaults yet. I'll let it run overnight.
Someone more senior might know.
Anton.
