couldn't spawn child process, Proxy error

CRB

hello,
we are on teamsite 5.5.2 on W2k, and TS proxy service went down, and had to restart, just searching for the root cause, and i am not familiar with this error, has anybody seen it before? or has an explanation to this error?

Hmm, could be a number of issues including system (memory, processes, etc). I would also check the script d:/iw-home/httpd/iw-bin/iwwebd_error.ipl and make certain it is good and has not changed.

BTW, have any of the TS accounts (root, iwuser) had their shell changed ? I have seen issues using bash with 5.5.2 for iwuser and/or root.
