Hi Rene,
your answer to one of my previous mails was, that my problem is due to
problems with my destructors, but:
1) As you stated in another mail, reading won't call a destructor for
each mail.
2) see the attached classes/example. It is a very simple example. Copile
it and try 'create.C' first. Afterwards run 'test.C' and find out how
memory usage (and swapping) is growing very fast!
Maybe there is somthing wrong with the code. But I don't have an idea
anymore what can be wrong with 15 lines of code.
I'm using root 3.01/06, Linux 7.1 With Kernal 2.2 and Kernal 2.4.
Best regards,
Thomas.
