Bug Description

Binary package hint: libapache2-mod-auth-pgsql

I have web site (with apache2) and when I use a pgsql authentification to access it, I can see a (huge) memory leak.

I use libapache2-mod-auth-pgsql Version : 2.0.3-4build1. Gutsy-server.

Repport of "valgrind --leak-check=full --show-reachable=yes apache2 -X -k start"

Hi,

It looks like this bug could be a duplicate of Bug #224945, which actually points to SSL.

Would it be possible for you to retry this use case without using SSL? That would help narrow the issue to libssl, rather than libapache2-mod-auth-pgsql.

Thanks,
:-Dustin
