--- Comment #7 from Mark Whitis <whitis freelabs com> 2009-05-24 19:36:06 --- The situation is much worse than described in this bug report. - X server resident usage climbs to 500MB and virtual memory usage to about 1.3MB on my system. - The X server memory is NOT consistently freed when okular exits. This results in serious thrashing. This appears to be related to okular sharing its pixmap cache among separate okular instances, such that the total memory used by all okular instances is capped at 160MB (until things go wrong) using some sort of X server shared memory. Given that okular appears to share pixmaps between instances, this does not appear to be just an X server issue. Shared memory mechanisms tend to have semantics that allow resource consumption to persist after a process exits. This is an X bug AND an okular bug. Okular performance is set to normal. Ironically, the resource consumption appears to be related to an attempt to limit resource consumption across instances. If you weren't sharing pixmaps, running multiple instances of okular would result in huge consumption but it would be consistently released when all instances were closed.
