I have a CentOS 6 server with Apache and PHP. I run some application and can constantly reproduce this crash. After some sequential action the app dies and the only trace I found is the following message in error_log:[Tue Jan 05 16:39:45 2016] [notice] child pid 1636 exit signal Illegal instruction (4)I installed the same app to a different host and it works. For this reason I think the problem is in OS or Apache configuration. What could be the reason for killing this process?Update 1: Both hosts has memory_limit set to 128M Update 2: Disabling SElinux does not solve the problemUpdate 3: Update from pcre-7.8 to pcre-8.13 does not help
PHP app crashes: child pid exits with Illegal instruction (4)
