fault (11) Reproducible: Always Steps to Reproduce: 1.Restarting apache 2.Waiting few hours 3.error-log reports segmentation faults Actual Results: Added pid in logs to see which process/page was causing faults: Segmentation happens after different random page is completely served, called mainly from phpbb3 Already tested these changes without any result: Disabled ad unistalled APC Changed in php.ini variuos values for: ;output_buffering = 4096 ;output_buffering = 16384 ;output_buffering = 8192 output_buffering = off ;memory_limit = 128M memory_limit = 256M Changed in server-tuning.conf: #MaxRequestsPerChild 10000 MaxRequestsPerChild 2048 #MaxKeepAliveRequests 100 MaxKeepAliveRequests 256 #KeepAliveTimeout 15 KeepAliveTimeout 5 Disabled in phpbb3: Gzip output compression: off Modules
