There's file on trailing-egde:
ftp://ftp.trailing-edge.com/pub/rsxdists/rsx11mplus_4_6_bl87_dsk.zip
It contains rsx11mplus_4_6_bl87.dsk disk image.

Incidentally, is it possible to SYSGEN a fresh system to a clean disk image from this RSX-11MPlus 4.6 image?

I ask because I'm fed up with being stuck on 4.2 and having to tell my PDP-11 sims it's 1985 :D I'd much prefer a Y2K compliant version of RSX-11M Plus, which 4.6 is, but would like it SYSGEN'd to my emulated system on a fresh drive if possible.

As far as I know (I haven't looked thoroughly), it is a complete system. So you should be able to do a SYSGEN just fine.

Has anyone using the above 4.6 system had any issues with the following. I periodically get the message on the console:

11:37:20   SYSLOG -- 70. *ERROR* On scan file open
11:37:20   SYSLOG -- 4. FCS I/O error code = 334
file: DU0:[???,???]SYSSCAN.TMP;1

It repeats dead-on 5 minutes according to the timestamps, which suggests it;'s something periodic the system is doing, and is nothing to do with the SYSGEN that's running at the moment.

It seems to be having a problem accessing some kind of temporary file? Do I need to worry about it or can I safely ignore it? IIRC it happened to me when I used 4.2 at some point too, but on totally different SimH emulation setups. Once my SYSGEN has finished I'll try creating a new user and logging in there to see if it still happens.
