EPERM occuring while starting our application

[Laurent Laperrousaz]

Our application runs many processes. they are launched and supervised by a dedicated process.

SOmetimes when a process crashes, the superviser restarts this process and it may happen that the restarted process gives "not owner " error in the log. If we kill the process again, it restarts ok.

These processes open 3 files for reading configuration purpose, 3 ORACLE connections, and a socket (INET) for inter-process dialog.

Here are the ulimit of the user that launches the application:
# ulimit -a
core file size (blocks, -c) 2097151
data seg size (kbytes, -d) 1048576
file size (blocks, -f) unlimited
max memory size (kbytes, -m) unlimited
open files (-n) 2048
pipe size (512 bytes, -p) 16
stack size (kbytes, -s) 131072
cpu time (seconds, -t) unlimited
max user processes (-u) 401
virtual memory (kbytes, -v) unlimited

What could cause this erratic EPERM error?

Hi

Which OS and Oracle version do you have


Also what does getprivgrp give for the group involved. Maybe you have a memory lock which does not clear quick enough and only on the second try can it run.
