on a recent default installation on Ubuntu - 14 LTS and 1.2.9 we encountered lots of segmentation faults:
php5-fpm: segfault at 7f45016b7021 ip 000000000070cb99 sp 00007ffd9d87ced0 error 4 in php5-fpm[400000+800000]
the entire domain is down until we re-start Apache. We know that the segmentation fault is possibly caused by PHP based file downloader(Using a 8MB buffer), in detail, its triggered by users, downloading large files through PHP.
It happens every 10 minutes and I am wondering what to do now!?
all on default, nothing changed.
Any hints are welcome. If we could change to good old apache PHP module, I think that could do; just don't know how!?
