Hi All,

I have performed a upgrade from Aveksa 7.0.0 to Aveksa 7.0.1 after the upgrade I am facing the error like("Su : Cannot set user id : Resource temporarily unavailable") mentioned in the below screenshot when i'm trying to restart the server.I have tried setting the limit to higher value but no luck.When I check the status of the application its showing as running and I can access the same through browser.

And also the few of the collectors are getting failed with unknown error code not sure whether it's happening because of this.If anyone have faced the same kind of issue please let me know your inputs.

Many thanks !

Note : Attached the recent server log extracted with debug mode ON for more reference.

To many processes have been started from the oracle user:

You can check how many with the following command: ps h -Led -o user | sort | uniq -c | sort -n

If this is sky high you might want to raise the limit of processes the oracle can start or check for the rootcause of the amount of processes started.

In your first post you execute: ulimit -Su 2000 before starting the server. Iirc this command limits the number of processes the oracle user can start? Try increasing the number here and try again.

I tried Increasing the limit to 385678.But still no luck the value got updated with the new one(3845678).

But still getting same error while restarting. Do we need to reboot the server after updating this value ??

Add the following parameters in limits.conf file and save the file.

Then restart the aveksa server

# vim /etc/security/limits.conf

Add the following line

--------------------------------

oracle soft nproc 10240

-----------------------------
