SNI vhost selection fails intermittently

Description

jomat reports some problems with the server at web0.jmt.gr. it has a single IPv4 address, with several name-based vhosts. the default vhost is www.jmt.gr. other distinct vhosts include 0.jmt.gr and l.jmt.gr. They use SNI to distinguish them.

Using mod_gnutls 0.5.10+lots of git revisions (close to what i'm hoping will be the 0.6 release), against gnutls 3.2.4-4 and apache 2.4.6-3, when the server starts up, everything is fine.

then, after a little while, sometimes selection via SNI starts to fail, and the default certificate is presented instead.

We haven't been able to track down what causes it yet.

It happens regardless of whether one is using openssl s_client or refreshing a web page.

we probably need a test for this.

jomat adds:

17:50 < jomat> I have never seen the problem on other vhosts than pad.jmt.gr and tagr.jmt.gr
17:50 < jomat> and these are the only two vhosts using mod_proxy
