Has anyone else seen or experienced persistent memory leaks with ubuntu 32bit or 64? I've literally had issues with it that may or may not be particularly ubuntu issues back to 7.04 that I first noticed. The only thing really in common system-wise is the hardware, and I somewhat suspect it's Nvidia driver related, but nothing really indicates any particular app. My primary desktop I use heavily just about anything, but I have another system that's sole purpose is to play movies and music on my TV I do almost nothing with that experiences the same issues, NVidia card as well. With compiz or without this happens. Only thing I haven't tried is running the NV drivers, but I rely on the acceleration far too much on both systems.
What I have noticed is there are no direct applications hogging memory via top, rather it seems virtual memory ends up simply taking over all physical memory and keeping it as "inactive" via "vmstat -a". Signs of this include firefox flipping out, rendering/scaling video larger than default, and just anything else that requires excessive memory use having issues. I graph my physical memory usage via snmp, and I can pretty accurately gauge how long I have until I need to do a hard reboot to reclaim the "inactive" memory. It mostly works even memory starved in this condition, just limits my usage, and even restarting x doesn't help. Interestingly enough, neither system ever swaps at all... Has anyone successfully ever dealt with an issue like this killing virtual memory? I really can't imagine I'm the only one... I've hunted far and wide of the great interweb for a way to release the "inactive" memory, as I'd even just go so far as to purge it once a day via cron if I had to, but I can find nothing of forcefully clearing inactive/dirty virtual memory space. I've seen others complain of the same behavior, but have only seen the same rhetoric that "trust linux virtual memory behavior, that's what it's supposed to do". Act like a stupid windoze me install and reboot daily? I think not... -mb --------------------------------------------------- PLUG-discuss mailing list - PLUG-discuss@lists.plug.phoenix.az.us To subscribe, unsubscribe, or to change your mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss
