Ive been noticing very large core. dump files (74MB each) in my public_html folder. On discussing with the hosting company, they say the issue is caused by the thesis open hook script.
This is what they said:
The trace is indicating that the application was killed with a signal 11 which means that it attempted to access memory that was non-accessible, this is normally caused when a script is attempting to use to more memory than alloted.
The application wrote the dump file after php crashed and reported the error to your error_log.
[20-Jul-2010 13:37:39] PHP Fatal error: Out of memory (allocated 62914560) (tried to allocate 40961 bytes) in /home/arjwiz/public_html/wp-content/plugins/thesis-openhook/functions.php on line 1065

If there is a way to figure out what exactly is causing the dumps, or how to recreate it, it would be great, since I am sure a lot of people would be inadvertently affected by this.
