Thanks for the response Igor. I tried to get a core dump, following the procedure mentioned in cwiki, but could not see any files created. Also, the crash seems to have been recorded in /var/crash but I could not find the vmlinux file on the system or online to create the crash report.
Due to time constraints I have moved the traffic server from a CentOS 6 machine to Fedora 12. Also, I have upgraded to the latest 3.0.2 version (which also crashed on CentOS 6). The system is working fine now. Wish I could be of more help with the bug report. I will try to recreate the scenario and file the report when the deadlines have passed. - Sid -----Original Message----- From: Igor Galić [mailto:[email protected]] Sent: Wednesday, December 07, 2011 12:47 PM To: [email protected] Subject: Re: Traffic server 3.0.1 crashes for low traffic generated using Apache Bench ----- Original Message ----- > Hello all, > > I am new to Apache traffic server and have downloaded the 3.0.1 > release on my machine. > My machine details: > Linux 2.6.32-71.29.1.el6.x86_64 #1 SMP Mon Jun 27 19:49:27 BST 2011 > x86_64 x86_64 x86_64 GNU/Linux > > I did the quick install mentioned in INSTALL file > ./configure > make > sudo make install > > I have an origin server (Apache webserver) on another machine.

I don't see a crash report, or a core dump :-/ Can you please recompile with --enable-debug and see how that changes in that regard? (Generally, see https://cwiki.apache.org/confluence/display/TS/Filing+useful+bug+reports for how to fill useful bug reports) n.b.: I'm releasing Traffic Server v3.0.2 tonight, if no one objects during my dinner break.
