nsrdisp_dd
Networker 19.3
OS: Linux
I'm just wondering - what is this process (nsrdispd)?
When I run ps -ef, I see multiple instances of this process' offspring - about 18 nsrdispd_dd processes, two of which are more than a month old.
From the Admin guide, the definition given for nsrdispd is: "Handles RPC-based calls for the nsrd process from remote third party processes". Not sure what might constitute a remote third party process.
The reason I am curious about this is that on another Networker server (which is much less busy), the parent process (nsrdispd) exists, but there are no nsrdisp_dd child processes at all. As far as I can tell, there is no noticeable performance impact - I'm just curious as to the difference where one Networker server has a bunch of these child processes, and the other has none.

Assuming you are running the NW server on linux, if you run "nsr_shutdown -l", would list the running processes from NW. It will show the correlation of which process is under control of which process (and their process ID's).
The nsrdisp processes are directly linked to making Vmware based image level backups. Only a backup server that actually makes vproxy based backups, actually shows more than only the nsrdispd process.
If those nsrdisp_dd or other nsrdisp processes should be running is not clear, as besides nsrdispd and nsrdisp_nwbg they are not explained (and even those rather limited). A KB article about a memory leak of nsrdisp_nwbg states it as "NetWorker dispatcher process".
In a NW19.3 server running since march, connecting to 2 VC's:
