So recently i installed newrelic. After i installed it, and i left it for some hours, my stderr.log had ton of "Child process with pid: 2968 was killed by signal: 15, core dump: 0" lines. +- 20,000 lines there. I am not sure if it is related with newrelic, but is litespeed incompatible with newrelic? Is there any way to make the error log clearer? Is creating a core dump will makes easier to analyze the error? One thing that i notice, after installing newrelic, almost everytime (75%) after i open SSH connection, or i clear my APC (in short the server absorbs more load), the stderr.log grows with that line.
