Updated by David Goulet about 12 years ago
- Status changed from New to Confirmed
- Priority changed from High to Normal
We are aware of possible memory leaks in the session daemon and relayd. Before 2.1-stable release, they will be fixed.
I'm changing the priority to this one to Normal since it does not break any features.
Thanks for the valgrind report!
Updated by David Goulet about 12 years ago
A lot of fixes were pushed upstream.
I'm keeping this bug open to remind us to check for memory leaks before any stable release.
Thanks!
Updated by David Goulet about 12 years ago
- Status changed from Confirmed to In Progress
Updated by David Goulet about 12 years ago
- Status changed from In Progress to Resolved
We are about to release 2.1-stable and memory leaks were audited.
If you find more at some point in time, don't hesitate to open back this bug or a new one!
