Hi,

I keep getting this error message while runnins some basic commands:

-bash: fork: retry: Resource temporarily unavailable

I have tried to check the ulimit of the user and it seems ok..

ulimit -a
core file size          (blocks, -c) unlimited
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 0
file size               (blocks, -f) unlimited
pending signals                 (-i) 238128
max locked memory       (kbytes, -l) 64
max memory size         (kbytes, -m) unlimited
open files                      (-n) 1024
pipe size            (512 bytes, -p) 8
POSIX message queues     (bytes, -q) 819200
real-time priority              (-r) 0
stack size              (kbytes, -s) 10240
cpu time               (seconds, -t) unlimited
max user processes              (-u) 1024
virtual memory          (kbytes, -v) unlimited
file locks                      (-x) unlimited


> ps -ef | wc -l
176


Any idea on why this is happening?

Tks,
jaoo

I have raised the max user processes to 2048 and the problem seem to be gone...

The question now is: How do I make this change permanent for my user?

I used ulimit -u 2048... but this will not be permanent...

Tks,
Joao

Edit /etc/security/limits.conf and add or change the soft limit for user process:

user               soft     nproc            2048

"Soft" limit is the value set at login.

Since you were able to raise the limit by "ulimit -u" there's obviously no need to adjust the "hard" limit (the value up to which the limit can be raised by the user with "ulimit -u").

'ulimit' is a shell command that changes only the shell windows you are in. To change the soft limit permanently, you need to update limits.conf as suggested by wmp and run ulimit -Sn.
