Cannot fork NETIO process ([12] Not enough space)=> aborting

[Anoop P_2]

Hi All,

We have a K580 11.11 system with 4 CPUs and 4 GB Physical Memory, running Oracle.

The system have been running fine for the last 100 days, but yesterday the backup (omniback) failed with the following error:

Cannot fork NETIO process ([12] Not enough space)=> aborting

The swapinfo -t output is as below:
TYPE AVAIL USED FREE USED LIMIT RESERVE PRI NAME
dev 2097152 1025528 1071624 49% 0 - 1 /dev/vg00/lvol2
dev 2097152 1028712 1068440 49% 0 - 1 /dev/vg00/lvol12

total 7426836 5849248 1577588 79% - 0 -

The backup was fired yesterday night, but the output above is of the day time. We have a system to archive the system performance, and according to it, the memory and cpu utilisation have never been above what is current.

uptime
1:54pm up 107 days, 18:17, 1 user, load average: 0.01, 0.01, 0.01

The glance and top outputs are attached.
Please suggest a way to resolve the situation.

Thanks in Advance

Hi Anoop,

Check your nproc and maxuprc values. I feel, the nproc value has to be increased.
maxuprc is dynamic, so try changing this first.

hi Anoop,

Have a look around your nproc kernel parameter. It might have reached the limit during the backup procedure

with best wishes

System Table Available Used Utilization High(%)
--------------------------------------------------------------------------------
Proc Table (nproc) 4116 177 4 4


Now, thats the nproc value which I have. I'm not quite convinced that all of what is available could have been used up.

Please suggest.
