Flow Buffer Full



(I'm sorry for not adding this to an appropriate prior entry, but for some reason if I search for a thread, the website logs me out and I can't reply.)

Anyway, we're getting the PE110 Flow processor buffer full error. I've tweaked what we're tracking so hopefully that will help, but I'm wondering if there's just some way to increase the flow buffer. We're running PRTG on a dual Xeon X5650 server, 6 cores per CPU, and 24GB RAM. CPU utilization never breaks 40%, and we're a relatively small environment. (3000 sensors, about 30-40 mb traffic being sniffed) Seems like we should be able to sniff this amount of traffic without too much problem.

Thanks! James

It would seem PRTG is not able to process the flow - this does not only depend on the traffic, itself, but also on the filters and toplists being used. Check if the behavior persists if you reduce the filtering / toplist parameters.
