no free slot in process-info-table

Hi,

 

i am getting below error

 

/sbin/dmesg - > /var/opt/OV/log/OpC/dmesg.out. (OpC30-127) no free slot in process-info-table (OpC20-401)

 

It seems that

"no free slot in process-info-table means that the operating system does not have enough free space in the process table to launch another process."

 

So in that case i believe we have to extend nproc kernel value.

So much i can put this value or any other kernel paramter do we need to change to resolve this issue? 

 

 

#-> kmtune | grep "nproc"
nproc                    4864  -  (768+8*MAXUSERS)

Sounds right.

What is the value of MAXUSERS?

 

If you were on 11.23 or later, you could use kcusage(1m) to get an idea how close you were to the limit.

Also on 11.23, nproc(5) is a dynamic tunable that defaults to 4200 and can be changed without a reboot.

Why do you think there is one, other than a crystal ball?  :-)

As I mentioned above you can set it larger then monitor the usage, in case your loads change.
