[Zope-DB] db2: accumulating connections

[Stephan Herschel]

Hi,

We've got a db2 database which we access with zope. It seems that the 
Zope-server is regularly opening new connections but never closing them. 
I've already looked into the database-adapter, but to me it looks ok. 
Maybe somebody can explain to me how Zope works in this respect or tell 
me where I can find documentation? When is Zope supposed to open a new 
connection? When will it close an open connection? What classes are 
involved?

Thanks for any feedback,
Stephan
