ReportCrash analyzes crashing processes and saves a crash report to disk. A crash report contains information that can help a developer diagnose the cause of a crash. ReportCrash also records the identity of the crashing process and the location of the saved crash report in the system.log and the ASL log database.

I’ve recently been having problems with “reportcrash” taking up a lot of resources, even when an app hasn’t crashed. This has stopped that from happening.

Thank you.
