interesting, I've never seen this message before ;(
colmux always used the threads package, but the is_running() I added in
newer versions to deal with threads more cleanly, so I guess that's your
problem, you must be running an older threads module.
I can see from colmux -v that I'm running threads V1.83, which version are
you running? one of the tricks for great support it having colmux report
the version of threads it's using, just like collectl reports versions for
zlib and hires. if you've tried colplot yet it also tells you the versions
of gnuplot it's using and whether gnuplot configured for png and/or x11
support ;)
