** Description changed: Hello, I observe random segfaults in PHP running as Apache module. I see Segfaults in Apache error log, I have collected multiple core dumps which indicate that the crashes happen in zend_stack_push() or zend_hash_find(). It seems that the crash happens at scripts compile time since in all the cases, I see the compile_file() function at some level of the backtrace. It is a low traffic website, 30-40 page hits /minute, VM hosted by Digital Ocean. Initially the problem was on Ubuntu 14.04 then in order to exclude hardware errors I spawned another VM that is hosted also in DO but in another region and currently I'm running it on Ubuntu 14.10, segfaults still happen: # lsb_release -a No LSB modules are available.
