ODBC session storage

[Kristof Bajnok]

Hi all,

is anybody using SP on a Debian Wheezy on a multi-node cluster with ODBC
backend?

We've been trying it for weeks now, but after seemingly working for a
couple of requests, then on one node shibd segfaults [1], and oddly the
session gets invalidated on all hosts (whose shibd survive). It seems
that a segfault only occurs if multiple hosts are used concurrently, but
unlike [2], it's very frequent, a crash can be reproduced with a dozen
page loads.

Unfortunately I'm not on a supported version (it's 2.5.2 from wheezy
backports), therefore creating a proper bug report would be quite a bit
of work. I'd look for the solution elsewhere if others could confirm it
works for them.
