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.

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.
