As noted memory usage won't particularly drop when a capture file is closed.

However, if memory usage increases significantly each time a file is reloaded
(^R) then that should be looked at.

Please (Thanks).


A number of these types of memory leaks have been fixed in the past.

See, for example, Bug #2375
