in thread Parallel::ForkManager eating up Resources?

The reason I'm doing that is cause I've read, on node Using fork with DBI to create simultaneous db connections., that DBI hates forking and you must use a new DBI connection for each child. Else you'll get DBI stepping on it's feet and causing unpredictable results.

Initial thought of creating the script was to run a child for each system; each system runs aprox 45 seconds upto 1 minu 30 seconds before it finishes.

for($i = 0; $i < $numchilds; $i++) {fork;  connect; while (get_task) {run_task}; disconnect; exit;}

You're suggesting taking the pool of tasks, split them into 5 arrays and then run them?

My tasks is updating a load of 100+ server stats in a database. I'll have to use some kind of splitting to split the array of hosts into 5 arrays (as evenly as possible) for splitting into individual forks.

That's a possiblity...

Thanks, I'll try that.
