Hello list,
I use flow-control from about 1 week. My OS is FreeBSD 6.0-RELEASE #0
for AMD64. All works fine but yesterday I found this in dmesg:
Jan 4 21:30:58 katana kernel: swap_pager_getswapspace(16): failed
Jan 4 21:30:58 katana kernel: swap_pager_getswapspace(12): failed
Jan 4 21:30:58 katana kernel: swap_pager_getswapspace(6): failed
I have 512MB RAM and 2GB swapspace
On this PC I have squid-cache running, but when check which program use more
memory I found this:

My starting line for flow-capture is:
/usr/local/bin/flow-capture -p /var/run/flow-capture.pid -n 287 -N 0 -w
/var/log/netflows/ -S 5 /127.0.0.1/8899
Is that huge memory usage is memory leak or I do something wrong ?
There could be a 64-bit problem. Our setup has some 32-bit collectors that
feed (among other things) a 64-bit cruncher. Building out the 64-bit
cruncher lead me to finding some 32-bit vs. 64-bit bugs:

But I haven't had to deal with flow-capture on 64-bit....
Is anybody out there running flow-capture on amd64/x86_64 or another 64
bit platform?
I think the easiest way to start looking at this would be to run
flow-capture under a memory debugger of some sort, like efence
(Electric Fence Malloc Debugger).

I'm running flow-capture on AMD64 on Fedora Core 3 with no problems.
The only issue I run into is lack of disk space! Sometimes 50GB is not
enough!
