I've had the proxy handling about 5000
hosts simultaneously. On Linux, though. 

I have not heard of such
behaviour before, and I am sure there must be others running the proxy
on Solaris in a similar setup. If you can make it happen again, please
do a "kill -USR2" on the xymonproxy process to toggle debugging on/off.


None of the Xymon tools are multithreaded - so far I have stuck to the
traditional Unix way of doing things.
