+++RPC Request rejected outstanding threads+++

[Elif Gius]

Hi all,

I got following error message in the syslog:
Jan 16 21:55:03 xx syslog: RPC Request rejected outstanding threads: 250
Jan 16 22:11:54 xx syslog: RPC Request rejected outstanding threads: 250
Jan 16 22:14:00 xx syslog: RPC Request rejected outstanding threads: 250
Jan 16 22:29:17 xx syslog: RPC Request rejected outstanding threads: 250

In this time we had problem with one application which could not communicate with another server.

What does this error mean???
Why did it happen???

Thanks in advance.

In general these message look like your RPC based application failed to execute some remote procedure(s) on the RPC server side.

Without knowing details about that application a problem diagnosis is difficult. You would need to know what RPC program/procedure was actually rejected. Okay, you could at least try to reach the server's portmapper and ask for registered RPC programs (rpcinfo -p ), then have a look at the corresponding processes.

But troubleshooting beyond that level should be done by the application vendor/support, I believe.

Best regards...
Dietmar.
