httperf segaults

[jithin1987@…]

Using httperf @0.9.0

httperf  --timeout=10   --server=*host*  --port=80 --wlog=y,requests_httperf_Hindi.txt --uri=/ --rate=200 --num-conns=2000 --num-calls=1 --client=1/3 
httperf --timeout=10 --client=1/3 --server=*host* --port=80 --uri=/ --rate=200 --send-buffer=4096 --recv-buffer=16384 --num-conns=2000 --num-calls=1
httperf: warning: open file limit > FD_SETSIZE; limiting max. # of open files to FD_SETSIZE
Segmentation fault: 11
degreethem-lm:perf jithine$ ulimit -n
10000

However for a lower rate like 100 its works without segfault.

You should report the problem to the developers so they can fix it: ​http://code.google.com/p/httperf/issues/list

I will report the bug there also, but I am using the same version (v0.9) of httperf on a rhel 6 and 5.6 box with same parameters and I am not having a segfault.

Could you attach the crash log please?

BTW, the default FD_SETSIZE is 1024 and it can only be changed at compile time.

Is it possible for me to try out changing FD_SETSIZE when installing?
