ATS crashes under heavy load
Hi
I have been experiencing ATS crashes under heavy load testing - around
25,000 HTTP transactions per second.
The environment is a 4 core desktop running Centos 5.6, kernel 2.6.39.2
compiled with TPROXY support. ATS runs as a transparent proxy.
ATS was compiled with the following options: ./configure
--enable-tproxy --enable-libev
ATS version of this info is 3.0.0 (I have tested it on 3.0.1 as well and
the same happens).
Attached is the records.config of ATS
Following is the gdb info:
Program received signal SIGSEGV, Segmentation fault.
