The script is VERY memory intensive so it really works cygwin and the 2000 Server HEAVY. If I didn't scrub the memory four times a day, the box would crash - and did just recently when I had turned off RAMpage for testing.

I can DEFINITIVELY say that *something* within cygwin - or perl (using Cygwin's perl) - causes a very real and very measurable memory leak. I run a 24-7 automated FTP encryption architechture using cygwin cron which launches a perl script that automates telnet and ftp from the inetutils package. After each invocation, memory is lost. The only thing that keeps the box from dying completely is that in the very same crontab I call - four times a day - a memory manager called *RAMpage* which is also open source and can be invoked from the command line. This program frees up the lost memory allowing me to essentially run the server indefinitely. I would of course rather not have to use RAMpage at all - but since there's ongoing denial about the existence of "memory leaks" *somewhere* in the vastness of cygwin - I have no choice but to resort to that which *works*. Ah well, someday the denial will end, or the problem will get fixed unintentionally when some other change is made and the "cygworld will go on". In the meantime, I have a solution - kludgy you can be sure - but it works and has been doing so for nearly nine months.

"May be"? You run a bunch of programs, exit them, and Windows slowly loses memory after each exit? Hard to see how that's a cygwin problem. cgf -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/ "WellChoice, Inc." made the following annotations on 08/07/2003 12:55:14 PM ------------------------------------------------------------------------------ Attention!
