[dvd::rip] unknown master events?

Howdy all,

searched the mailing list archive and a bit on the web, couldn't find anything about this...

using dvdrip 0.98.4

I have 4 nodes in my cluster:

1. primary -- running FC5 2.6.16 x86_64 (3600+)
2. secondary -- running FC4 2.6.17 x86_64 (semperon something, sometimes i wonder why i bother with this one...)
3. secondary -- running FC6 2.6.20 i386 (old p4)
4. secondary -- running FC6 2.6.20-1ex x86_64 (3600+)

the following versions of packages:

during transcode jobs (running dvdrip as dvdrip -c) am getting a bunch of the following error messages:
Unknown master event NODE_PROGRESS_UP at /usr/lib/perl5/site_perl/5.8.5/Video/DVDRip/GUI/Cluster/Control.pm line 893.

Unknown master event J at /usr/lib/perl5/site_perl/5.8.5/Video/DVDRip/GUI/Cluster/Control.pm line 893.

etc -- these seem to get tossed every couple of minutes, but sometimes they come in clumps...don't see any ill effects from them, but thought if they were a problem someone out there would like to know

sorry for reporting this if this is something toasty on my side...

Regards,
