There was a bug in the Hobbit devmon collector that would cause a segfault if 
a repeater name contained a space. This has been fixed (to ignore lines in the 
rrd section of the report that contain more than two spaces) in svn.

The RC1 release contains the same version as the devmon 0.3.0 release (the one 
with the bug), but the final release of Xymon 4.2.2 should have the version 
that is currently in devmon svn.

There may be some problems with the format of the ifName values on your 
switches (they should normally not contain a space, but e.g. on the lastest 
Cisco IOS, ATM interfaces now have spaces in their names). Can you send the 
output of:

$ bb localhost 'hobbitdlog devicename.if_load'

(where devicename is the hostname of one of your 3com switches) run on your 
hobbit display server

?
