I am definitely not exceeding that many processes. Isn't there a way to count how many processes are being spawned during the run?

Well if you're not sure how to count processes then you can't be sure you're not exceeding that limit.

I checked one of my 8.5 servers now where all credentials are mapped to dsadm and grep'ed on that ID as the process owner. It found 896 processes running, and it's after hours at the moment. I have processes(per user) set to unlimited.

You can grep on other things too, like osh. The -i flag is for case insensitive grep. AIX example:
ps = process command
grep = filtering command
wc = word count command with -l for line count option (gives the count)

or
Suggest running these commands on both servers before and during the times when you kick off 25+ jobs at once.

You might want to throw in a "grep -v grep" for good measure.

Or
if you dont want to type more...

Hi,

I don't know if I'm off-topic but could this be related to a wrong parameter value in the uvconfig file?
Previously I got trouble with the number of opened file descriptors (DS could open as many as the OS permitted). Then I changed values in the uvconfig according to IBM's proposal and get it worked.

Eric
