Igor, please notice that Meny used feed file with 5 sockets and run the server
with 5 threads.
After you fix it, please see if this also fixes Alex Seydin's issue and let us
know.

I can not reproduce issue you described with sockperf 2.5.25 on following
system as
- Linux version 2.6.18-164.el5 (mockbuild@builder10.centos.org) (gcc version
4.1.2 20080704 (Red Hat 4.1.2-46)) #1 SMP Thu Sep 3 03:28:30 EDT 2009
- (GNU libc) 2.5
Steps to reproduce:
- launch: $sockperf sr -f udp_10.txt -F s --threads-num=10
- launch: $sockperf pp -f udp_10.txt -F s
- ^C for server after client completion
I suppose seeing backtrace (thanks for that) fault could relate issue described
at
http://sourceware.org/bugzilla/show_bug.cgi?id=4509
Meny,
could you set more detail info about used system including libc version.
In addition,
check latest version of sockperf on your system as long as it should include
additional validation of TID before pthread_kill() call.

Meny,
Have you observed issue on different systems?
Could you please put core dump of the issue case on bgate into /tmp and send
info about used system and libc.
Thanks

Igor, I ran it on another O.S. same result.
Try ending server proceess (^c) after client finishes.

Meny,
I believe I do the same (see comments #3). I have experimented with different
combinations as 1000records/10threads, 10/10, 1000/100 etc.
It is possible that core dump helps to see root of issue. Send system info you
tried also (may be the issue is system depended).
Thanks

Meny,
Thank you for bt you sent but it does not make issue clearer.
Could you send output of 'uname -a' and 'ldd --version' from the hosts you have
used.

Modified thread termination procedure for multi-threads server mode in r46.
Meny,
Could you verify r46 for this issue.
