Subject Re: ldap server buffers search results?
Date Fri, 03 Apr 2009 11:11:56 GMT
Hi Andrea,

Just to let you know, this looks to be the same problem that is being 
discussed in my OutOfMemoryError thread on the users mailing list.

It still seems to be happening in the latest ApacheDS trunk.  I don't 
really understand why it is happening yet though.
