[PHP] PHP5.4 + Apache 2.4でSegmentation fault — digape.com

HTTP pipelining と Apache 2.4 (worker or event) + mod_php の組み合わせで問題があるようだ。

FreeBSD 10.0 Apache+PHP Segmentation fault | The FreeBSD Forums

56984 – Random and frequent Segmentation fault (11)

I think this is related to HTTP pipelining and Apache version 2.4
...
Segfaults for all tested version of php for apache 2.4, but never for 2.2.29.
Also, 2.2.29 outputs all pipelined requests.
...
Hopefully this helps.
I am getting a lot of segfaults these days.
Seems that HTTP pipelining is enabled for safari on iOS devices.
