This is not a bug report but just a heads up to see if anybody else has seen a similar problem.
Some of our gpc programs are what I would term as server processes. By that I mean that they are intended to run in the background for several days at a time serving requests that are passed to them in various ways. We have recently realised that these programs are steadily increasing their memory usage with cpu time used such that the system, in the worst case, runs out of swap space. The problem may well be in our own code but we have not yet isolated it. I just wondered if there was any other possible explanation eg something in the run time system or whether anybody else had seen similar problems? Any advice on strategies for isolating the problem would also be appreciated.
