win2k "resource" exhaustion problem - no Cygwin programs will run

win2k "resource" exhaustion problem - no Cygwin programs will run

[james pentland]

i ran my script again after killing all my other user
processes - firewall, virus watcher, pgp and other.

the problem persists.

it does, however, appear to be memory related.
as the script runs, physical memory usage climbs
slowly to 225248k (out of 261424k), at which point the
script dies.

i show some system statistics below.

Oh well.  We can't fix what we can't duplicate.

Why not try uninstalling the firewall/virus scanner, restart your 
computer, and try this again.

It looks like a problem several people are experimenting.
Lately, someone exposed a link between this problem and Agnitum Outpost
(a firewall) that seems to forget to free some resources. This sounds
plausible, from my point of view, as I also have Outpost and I'm
experimenting this problem.

[BTW, Rampage was evoked as a possible workaround, but it had no
positive effect on my system.]


HTH,

win2k "resource" exhaustion problem - no Cygwin programs will run

[james pentland]

dear Cygwin developers:

i have a bash script which apparently causes an
exhaustion of system resources.
which "resources" i am unclear about - it does not
seem to be memory.

the consequences of running it, at a minimum, are that

1) the script fails at some point,
2) no further Cygwin executables will run,
3) dialout to an internet service provider fails,
4) a number of non-Cygwin executables do not operate
properly.

below is a simple script which will make the problem
happen and a partial transcript of a Cygwin console
session where it is invoked.

do you have any ideas on this issue?
