Thanks Buchan. 

To close this thread off here and give others a chance to follow if this thread turns up in a search later, a bug has been created on the sourceforge project page.

Since devmon doesn't actually require a Xymon installation, the usual way to 
start is is from an init script. An example is supplied in the 'extras' 
directory. This is covered in item 6 in the docs/INSTALLATION file.

Don't we all. I fixed the more frequent cause of the 'devmon goes purple' 
problem before the release of 0.3.0 final, but this one is a bit more difficult 
to reproduce, and thus troubleshoot. So far it looks like the sockets used for 
communication between the master and the children stop responding.

Again, this really belongs on the devmon mailing list, or in a bug report.
