My memory usage climbs up to 78% and slows down my machine. It doesn't hang
but general performance of the server goes way down. I'm running RedHat 6.2
on a single Penium 550 Mhz machine with 128 Mb of RAM. I've also noticed
that over this last weekend, Flowscan was only graphing about 1/3 of the
traffic volume on our gateway interface. The graph and the memory problem
corrected themselves when I rebooted the server.

Subject: Possible Memory Leak
I've been running cflowd a little over a month now. The first week I ran
cflowd-2-1-a9 straight from the source. It ran about 4 and a half days
and then my machine locked up. (It's running on a dual processor
pentium with 128M.) The box had been running for months prior to that,
and this was it's first full-time application. I then heard about FlowScan,
so I went back to cflowd-2-1-a6, with the flowscan patches. This was
nice, but I still ran into the same behavior as before. About four days
into the run, the machine would hang. Having read about a possible
memory leak, I always kept a window running "top" open, so that I could
monitor the behavior of the process. Cdlowd seems to grab about 12-17%
of memory a day. Once the process reached about 78% of the memory,
the system would hang. A few days ago, I reinstalled cflowd-2-1-a9 with
the flowscan patches. I'm still seeing this same behavior. Is anyone else
seeing this?
