Subversion server is down

The subversion server is down. There is a problem with mod_gnutls that causes Apache to use 100% CPU and never finish any request. It started around 5 AM this morning (European time) and nothing I do seems to work.

#apache on irc.freenode.net isn'table to help either, so I am forced to take the SSL domains on the server offline while I investigate this issue.

I am getting really, really fed up with mod_gnutls. It is causing way more trouble that it's worth. Unfortunately it's the only way to have multiple SSL virtual hosts with just one IP address. The server that hosts subversion also hosts a few other websites which require SSL to work.

I will try to get the server back online as soon as possible.

Update 12:22h: The Subversion server is back. It turns out that there is a bug in libdb which causes gnutls to lock up when trying to write session cache data in some rare circumstances. I tried replacing libdb with memcached but unfortunately gnutls is built without memcached support on Debian Lenny.

Webserver relocation

In the week of April 14 our webserver will be moved to a new location. You should not notice anything of this since we can simply reassign the existing IP address to the new server, so no DNS cache needs to be updated. We will be upgrading our base platform from Debian Etch to Debian Lenny during the move. I will update this post once the move has been completed.

Update: The server move has been completed. Please let us know if you see any problems.
