It feels like an issue with the number of file handles or maybe the
number of tcp connections, but I can't seem to get the right formula to
fix it up.  Anyone have any suggestions?
It seems a little early to be hypothesizing causes with such a loose description of the failure.

Have you enabled --debug on the xymonnet process? That might tell you if the requests are all going out but the responses are not coming back. Or if there is a significant hicup in name resolution several times a day. Or . . .

If you run 'xymonnet --no-update' when the problem is occurring, do you see anything interesting in the output?

'twould also be helpful to know what operating system and network arrangement you have. Is this all Linux on VMWare with fake nics? Is your server an AX-400 on token ring?
