I get this error msg every time I try to run one specific problem. Don't get it anywhere else. Full error msg is as follows: ***STOP 0x0000003F (0x00000000, 0x00000011, 0x00000439, 0x0000CF87) There is no text like bla_bla_bla As there normally is I've spend the whole evening trying to work out what it is and so far ive come up with following possible causes: -The system Page Table Entries (PTEs) are depleted or fragmented due to the system performing a large number of input/output (I/O) actions. -A faulty device driver is not managing memory properly. -An application, such as a backup program, is improperly allocating large amounts of kernel memory But no idea how to find out which one of the (if any) problems are actually causing the error, or more importantly HOW TO SOLVE IT!!! Please help!
