From: adams at mars-project dot com Operating system: FreeBSD 4.10 PHP version: 4.3.7 PHP Bug Type: MySQL related Bug description: php Core Dumps randomly and kills mySQL
Description: ------------ We have a on-line game in production, it is a online text based stratagy game. Our tick file that runs every 5 minutes has a php core dump very randomly and at that exact same time mySQL drops its connection. The odd thing is that if you just cruise the page. It will never show this behavior. I would have to check with my team members if they are ok with giving you the cod but it is 100K+. The funny thing is the code will run, about 5% of it then just drop. Every time when that error occurs but it occurs so randomly we have not found a reason yet. We only have 5 test players so its not like we are overloading the system. Reproduce code: --------------- As per above. Expected result: ---------------- No core dump. Nor mysql connection drops. Actual result: -------------- Very random and not reproduceable core dumps. example of my logs both php and mysql crash at the same time but only php core dumps. System Error Log.
