HI Syed

Where you find this error?

This is related to dispatcher.
The dispatcher was unable to spawn a new shared server process to handle requests.

This problem is occurring because you are running out of resources on your machine that are required for the servers to startup.

Solutions:
1. Increase swap or memory.
2. Reduce the number of shared servers (dispatchers) that can be started.

Ahsan, thank you for ur response. when i check the memory resources availibility via swapinfo -m -t it provide the details. its using abt 34% of physical memory, reservce space is not allocated and its using the reserve about 27gbs . pls view the attached screen short from original post. thanks

Shalom,

There appears to be adequate memory.

I'd look at kernel parameters.

nfile
nproc
maxuprc
maxfile_lim

There is not a space problem in my opinion but a kernel parameter set too low.

Hi SEP,


Requested parameter values are.

nfile - 65536
nproc - 4200
maxuprc - 2048
maxfiles_lim - 4096

thnx

after increasing the Maxproc the problem subsided.
