Re: Worker dies with a segfault error

March 04, 2014 10:07AM
Hello

Below is the backtrace. I have seen the behaviour without eval and Postgres and I will try to take a trace tomorrow. In the debug log actually there is no error. Since I have only one worker the PID just changes to the new worker without any info. Since I am using nginx as proxy only I am suspecting that the error has to do with the proxy functionality.
