wotaskd is giving me lots of grief today. We have a installation

I wanted to add another machine to handle some load and this is a
virtual VMWare machine running CentOS.
You can see the config here:
http://vinta50.anchor.net.au:1085/cgi-bin/WebObjects/wotaskd.woa
But I cannot add it to Javamonitor on our existing FreeBSD host. The
error message is cryptic:
The wotaskd on vinta50.anchor.net.au is an older version, please
upgrade before adding...
But I'm pretty sure it is the right version. Anyway, older than
what? Given that port 1085 is now open to the whole internet (we'll
lock it down once this is solved), I can't see a connectivity
problem. But the major difference is that the new machine is in a
different subnet. We weren't ever using multicast anyway though.
I suspect some sort of a communication problem (IOException). A
timeout? The source for JavaMonitor and wotaskd is in Wonder. Have a
look at HostPage.hostMeetsMinimumVersion() to see why this is
happening. If it throws an IOException (caught by catch (Throwable
e) ), the it assumes the version is too old.
Also, I don't know if this is related, but it takes about 3 minutes
for wotaskd to start up on the new box. I can't see why and the logs
don't add much.

Any help at all is very welcome. I'm tearing out my hair on this.
The IP address and host name resolve nicely to each other which is
the usual problem with wotaskd.
I'd guess something is timing out. A DNS lookup maybe? Try adding
WOHost=<IP Address> to the wotaskd Properties files and see if that
resolves it. Then try again with the cannonical host name for that
machine.
