Clearing memory?

[Qiang Cui]

Dear all,

	We are using an Athlon based beowulf cluster to perform CHARMM
type of calculations (OS: Redhat 7.1). One issue that we noticed is that
the memory available to use seems to be decreasing all the time: our
machines come with 1GB of memory, but "top" tells us that the available
memory is only on the order of several hundred MBs even without any
serious calculations - it looks like that some blocks of memory were not
fully released after previous calculations. This problem forces us to
reboot the machine from time to time for large-memory calculations. 

	Any suggestions on how to cope with this problem? Thanks!
