your error message looks like a system error. Has your OS changed/upgraded? Fork processes limits changed? Are you sure the spawned (extenral) process does what it used to do? Perhaps No child processes - system limit? can help?

Also: your script upon entry forks. Perhaps print something when it enters/forks to count how many forks=children you have (edit: and print something when child exits/returns to offset), perhaps this is a problem caused by a sow-happy driver script.
