PHP 7 Segfaults

Hello, since we switched from PHP 5.6 to PHP 7.0.x (tried multiple Versions - now we are on 7.0.11) we get random segfaults with our CMS. Not predictable when they will occur or on which Script. (Sometimes a few Days no problems - sometimes 5 times a Day ...) Not 100% sure - but I believe that opcache could be the cause of the Problem - as a simple "opcache_reset();" is enough to get everything up & running again - no complete restart of Apache needed. Maybe someone more confident with Backtraces can point me in the right Direction with those Information: http://temp.in.futureweb.at/php/error.log Thank you Andreas Schnederle-Wagner Futureweb OG Innsbrucker Str. 4 6380 St. Johann in Tirol schnederle@futureweb.at www.futureweb.at
