[SR-Users] Memory leak in 3.3.4

Hello,

you gave only the first part of memory log output. The chunks listed 
there are from startup, thus not part of a leak, because they are not 
allocated again at runtime.

Can you give the full logs with messages from qm_status? The leaks are 
typically listed towards the end of those messages.

Yesterday someone else reported a potential leak when using perl module, 
so it might be something else there. I found one, which is related to an 
error case, but perhaps you don't get that, otherwise you will notice 
the error message.

Cheers,
Daniel
