I had a similar problem earlier, when running on an older server.

How are you doing the monitoring?

I do pretty much all of my monitoring using SNMP from the bigsister server.
I have ~100 hosts in one uxmon-net and ~70 network devices in another and
that is OK.

If you have slow devices you can run into problems if the uxmon process
is not able to process all its devices in 5 minutes.

You could try splitting the uxmon-net file in two (or more), that might
help to create some more multitasking (unless your server is completely cpu
bound, of course)
