More than one nsrexecd on Linux Red Hat system

Question

A system running Linux Red Advanced Server 2.1has recently upgraded to Networker version 7.3.3 (build 510). Since then there are five (5) nsrexecd daemons running.

[root@japetus nw733]# ps -ef|grep nsr
root 25336 1 0 12:57 ? 00:00:00 /usr/sbin/nsrexecd
root 25337 25336 0 12:57 ? 00:00:00 /usr/sbin/nsrexecd
root 25338 25337 0 12:57 ? 00:00:00 /usr/sbin/nsrexecd
root 25339 25337 0 12:57 ? 00:00:00 /usr/sbin/nsrexecd
root 25340 25337 0 12:57 ? 00:00:00 /usr/sbin/nsrexecd

When I start a backup from the backup server (Windows) another nsrexecd daemon is started. My question is why are there so many nsrexecd's and how can I get rid of them?

The kernel version is: 2.4.9-e.57enterprise

Kind regards,

Martijn

I recently heard one EMC guy stating that was normal under Linux (as hinted, no other OS exhibits this). I also believe I have heard no other impact has been seen due to this.

Did you check client parallelism? I don't think it makes sense but may be a parallelism of 5 has got 5 nsrexecd processes running for you. Is it hampering the backups as well?

Anuj, it's not hampering the backup. The system can maken backup fine.

I will check other Linux systems, but I think this is the only system that is experiencing this problem. You are right, there is no impact. The system can make backups without any problems.

I checked the other linux clients, but they all have just 1 nsrexecd. A collegue of mine suggested that it might if the system had more than 1 CPU's a nsrexecd is started for every processor. Unfortunenately the system concerned has only 1 CPU.

There are same Linux brand (with same kernel and other typical settings)?
