Re: proc full
I cannot see proc: table is full as you have 970 processes on 4200 which is the value of kernel parameter nproc. Maybe you see messages in syslog.log because in the past nproc limit was reached.
Also about shmmax the tunable can be changed immediately without reboot.
Best regards,
Fabio

Re: proc full
in the showed condition (1114/4200) proc table IS NOT full.
You should get the message "proc: table is full" when the value of the first column will be equal or almost to the value on the second column.
To get constraints about min and max of nproc read the following:
# kctune -vq nproc
Tunable nproc
Description Maximum number of processes on the system
Module pm
.........
Constraints nproc >= 100
nproc <= 30000
nproc >= maxuprc + 5
nproc <= nkthread - 100
nproc >= semmnu + 4
Can Change Immediately or at Next Boot
HTH.
Best regards,
Fabio

Re: proc full
consider that dmesg retains even old messages in its buffer, instead I don't understand what about syslog.log.
Do you see the message of proc: table is full right now into the syslog.log?
Could you please attach it here?
