A hint would be greatly appreciated.

I already asked this before, but unfortunately didn't get any reply yet, so here it comes again with some more details: I wrote a program that does a Monte Carlo simulation of ferroelectric switching using the gsl scientific library (Because I needed a good random number generator). The simulation is actually performed on 8-10 computers simultaneously, each of which runs a client program that does the math. The results are collected then by a server program via TCP/IP over our LAN when the clients are finished. This works all flawlessly, when each client does its own independent simulation and returns the final results after 6 hours or so. However, I run into problems when each client is given basically the same task (just with a different random number seed) and the intermediate results are collected by the server every 5 minutes or so to calculate an average over all the results obtained from the clients to improve the statistics. In this case the server program dies after 2 hours or something with : couldn't commit memory for cygwin heap, Win 32 error 487 The computer running the server program, also runs one client, and a couple more programs to keep track of which clients are online and to maintain a log file of the simulation currently being executed. All these programs run in an independent cygwin bash shell. I would greatly appreciate some comments on the nature of this error, and what might be the possible cause and remedy for it. In case more details need to be provided, I'll be happy to do this.
