From: rainer dot herbst at uni-potsdam dot de Operating system: Solaris 10 SPARC PHP version: 5.3.18 Package: Reproducible crash Bug Type: Bug Bug description:PHP 5.3.x failes with core dump
Description: ------------ We use PHP 5.3.x with Apache HTTPD 2.4.3 on Oracle CMT Sparc systems for our elearning system (Moodle 2.3). Quite often, some httpd processes fails throwing core dumps causing sometimes the Solaris Service Manager to bring the HTTPD into maintenance mode. Sometimes only one core dump is written, sometimes up to 6-7 dumps simultanously. As to show how severe the problem is - in 12 hours we get app. 50 core dumps occuping app. 20 GB and 2-3 service "transitioned to maintenance" messages. Both PHP and HTTPD were compiled using Solaris Studio 12.3. APC (3.1.9) is enabled.
