[itsdb] [incr tsdb()] and PVM problems

[Stephan Oepen]

hi mike,

those messages suggest your PVM daemon fails to start up, which in my
experience is typically related to an unclean shutdown and left-over files.
please check the contents of the $LOGONTMP directory, or maybe try a
‘make pure’ in $LOGONROOT.

if all else fails, what messages do you get when launching pvmd3 from a
command line?

i am using fedora 15 myself, so doubt that is part of the problem :-).

cheers, oe
