Hi Brian

With the current version of httperf I believe it is necessary (to sustain high request rates).

Thanks
Martin

Subject: [httperf] fd-unavail?

Getting this in httperf runs:

Errors: total 1117 client-timo 191 socket-timo 0 connrefused 0 connreset 0
Errors: fd-unavail 926 addrunavail 0 ftab-full 0 other 0

Problem is, I have:

brian at host:~$ ulimit -n
65535
brian at host:~$ cat /proc/sys/fs/file-max
697479

Is there something special about fd's with httperf?  This page:
http://www.cs.uwaterloo.ca/~brecht/servers/openfiles.html

suggests I need to actually change posix_types.h, which yeah - is 1024
- but...is that actually necessary?

Thanks,
Brian
