ERROR|error creating messaging thread (48): err (12)

Holler - Increase the NumThreads in  swentobjsv.cfg along with required StackSize. The main problem with this error is of the threads starting up.  

Please remember that the Default Values for NumThreads / StackSize is calculated based of the system resources.  

NumThreads - 

If NumThreads is not set, then it is calculated with the formula - 

NumThreads = NumCPUs*DFLTMAXTHREADS*Multipler
Multipler = MAX (1, (2.4 - LOG (NumCPUs)))
where:
• NumCPUs is the number of processors on the system.

• DFLTMAXTHREADS is the default value, 5.

StackSize - 

This is set to login users thread stack limit.
