Package: php5-fpm
Version: 5.4.4-14+deb7u9
Severity: important
Dear Maintainer,
I'm running nginx with php5-fpm. Seemingly random I see 'Bad gateway' errors
when browsing a wordpress based blog running on the server. According to
syslog this is caused by php segfaulting.
My debugging skills are pretty limited, but this is what I got by following
the guide on php.net:
Program terminated with signal 11, Segmentation fault.
