Well, you seem to managed to fork the post anyway ...

You might try being a wee bit more descriptive about what your problem is so that we have at least the slightest clue.

Apologies for forking details in the previous thread

Our application is CHUI Application hosted on Solaris server. We recently upgraded our application from 10.1C to 11.6.

Screens are crashing with a below-mentioned error after application upgrade to 11.6

SYSTEM ERROR: Too many sub-processes, cannot fork. Errno=12. (358)

Thanks & Regards,
Muralidhar

You exceeded the kernel parameters Maximum Number of Processes (NPROC) or System Swap Space (NSWAP). If this problem persist and occurs when your system resources are very busy, make the appropriate kernel changes and monitor the problem. If the problem continues to persist, contact your dealer, your country's PROGRESS subsidiary, or Progress Software Technical Support.

What are you kernel parameters current;y set to?

Hi Cecil ,
As Suggested by Progress increased swap space but issue not resolved

Solaris is infamous for this. You need a *lot* of swap on Solaris.

I'd migrate to Linux. Solaris is a dead-end.

enabling client logging or generating client protrace files should help look at the call stack to see if it is what you expect.

Thanks for thee Advice CJ and Tom

Tom,
Do you face Memory /fork issues while migrating on Linux ?

 

[TomBascom]

No.

Linux uses optimistic swap reservation while Solaris is (very) pessimistic.

I can only second what Tom said. Solaris is a PITA when it comes to swap space.
