We still don't have enough information, or perhaps not the right one. 
OOo in general definitely does not have a memory leak of that kind - you 
wouldn't be the first to find it in case of. I know that OOo is used as 
a server in a lot of installations without such huge problems. So there 
must be a particular issue that is special for your setup.

So let's summarize and see where we can make progress. We should try to 
describe everything exactly as possible.

You are talking about a "document server" and a "DocumentLoader". The 
latter seems to be a C++ application and the former seems to be an 
instance of OOo that is talking with the C++ application though a remote 
UNO bridge.

The DocumentLoader seems to use this instance of OOo to load a ppt file 
and then it seems that something is eating up your memory.

Is that the correct picture? If not, can you describe it better? 
Especially we need to know most exactly how OOo is used in this scenario.

Next question - this "something" that eats up your memory - did you 
verify that it is the OOo process whose memory consumption goes through 
the roof?

Another question: did you try the same with other kinds of documents 
(not ppt)?

Regards,
Mathias

I use it for the OOo lists and only rarely read other mails sent to it.
