The server upgrade and the upgrade of the KForge software from 0.12 to 
0.13 is now complete and the system appears to be fully working again. 
However we did run into several issues a couple of which we have not yet 
been able to fully resolve:

1. The debian etch combination of trac (0.10.3), modpython (3.2.10) and 
apache (2.2) seems to result in some rather weird behaviour by trac with 
some parts of the trac system intermittently failing to load.

This is a well-known 'trac' problem which seems to arise from threading 
issues between modpython, trac and subversion. We have applied some of 
the suggested patches but as yet this has not fully resolved the issue. 
We are continuing to work on this and hope to have this sorted soon. In 
the mean time please be aware that trac may not functioning entirely as 
it should.

2. There appear to be some problems with certain subversion clients 
accessing svn repositories over ssl. In particular on mac osx I have 
been experiencing errors of the form:

svn: PROPFIND request failed on '/kforge/svn/!svn/vcc/default'
svn: PROPFIND of '/kforge/svn/!svn/vcc/default': SSL negotiation failed: 
SSL error: decryption failed or bad record mac 

It has been established that this problem does *not* occur on ubuntu 
edgy and standard debian machines. Searching on the net leads us to 
believe this may be caused by incompatibilities between the upgraded 
openssl library on the server (debian etch). If you experience problems 
please report them here.

Finally, if you experience any other problems in using the 
KnowledgeForge service please let me know so that we can try fix them.
