Hi,

Thanks for the help, will give me something to investigate. For now, simply turning the number of threads down to 5 seems to have helped.

I do use $threads$threadno->kill('STOP'); in the code to stop threads that go on for too long. I then trap this with $SIG{'STOP'} = sub {$end_ne=1;}; and test for the value of $end_ne in the code at the end of any part that may take a while. Could this be causing the semaphore errors?

I can't just kill the long running thread a re-create it, I need to simply back out of the current NE in that thread and set it to a state that the handler can pass it a new NE to try. Unfortunately Perl uses memory up (~5MB from memory) every time a thread starts and doesn't release it until the whole program exits. Given the script could run on 5000 NEs, a major network interuption could therefore see nearly 5000 threads created and killed!!

I'm not typing ^C and noone else is logged in.

Thanks

Graham
