Memory buildup under Linux

[uktony]

I have a server running CENTOS5 and 4 Transcoders as AutoDJ's and One Shoutcast1 stream server.

The memory use rises to almost my limit and then drops to a low level and then rises again. This looks like a memory leak, but I cannot think one exists as it would have been spotted by now, and fixed long ago.

So is there a command I need to add to get it to dump used memory?

I only get this on one server, the rest all have a more or less constant memory load. Is there a Max memory used command?
