I was annoyed at this too.

Got a clue from...  line 148 at
http://fossies.org/unix/privat/xymon-4.3.10.tar.gz:a/xymon-4.3.10/web/showgraph.c

Had good luck getting rid of these, by going to the $XYMONTMP directory and
deleting sockets
named 'rrdctl.<pid>' - where pid did NOT correspond to any running
xymon_rrd processes.

$ cd /export/xymon/server/tmp   ### This is XYMONTMP in my shop
$ ls -ltr rrdctl*
