** Description changed: Memory leaks in xorg-server while video chat is running in skype 4. To reproduce: 1. Update to the current version of 10.04.4 (i386) 2. install skype 3. run video chat. - Xorg will use all possible virtual memory in the system and OOM will - kill skype. + Xorg will use all possible virtual memory in the system and OOM will kill skype. + Xorg did not release memory upon skype termination. - This is degradation, possible introduced by one of the latest updates. + Looking in old bug https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/565981 + I found that /sys/kernel/debug/dri/0/gem_objects reports negative number of "object bytes". + + This is degradation, possible introduced by one of the latest updates. Same configuration, with same version of skype 4, was running stable till I did scheduled update week ago. I perform an update once in one-two months.
