Sounds like your problem is due to heap fragmentation. The only solution is
to use a best-guess for the approximate size of the memory stream and
initialise the memorystream to that to start off with. For example if the
average size of your class is 68 bytes, then initialise the memorystream to
array.Length * 68. Or some such thing.

Still, a testcase may prove useful.
