    That is a common problem if you have a lot of custom code wrote by not very competent developers. There are a lot of IDisposable objects in Sharepoint which should be properly disposed. So, if someone violates this rule, especially in webparts which are accessed very often, the memory could be trashed with such objects, which in the most bad situations can even cause OutOfMemoryException. There can be other situations, but this is the most common.
