[Bug 217027] New: memory leak in NetworkManager
https://bugzilla.novell.com/show_bug.cgi?id=217027 Summary: memory leak in NetworkManager Product: openSUSE 10.2 Version: Beta 1 plus Platform: Other OS/Version: Other Status: NEW Severity: Blocker Priority: P5 - None Component: Network AssignedTo: tambet@ximian.com ReportedBy: seife@novell.com QAContact: qa@suse.de CC: thoenig@novell.com OtherBugsDependingO 215208 nThis: Today, i did the following: - unplug my network cable - walk to the next office - replug my network cable - in the mean time, nm tried to connect to Wireless network "wpa2-test" (which does not work currently, since knm apparently never asks for the kwallet, but this is a different issue) - it does not automatically detect that there is a cable plugged, so i select "cable" in knetworkmanager - network is up, i am happy and go away. I come back after maybe one hour and find, that something is loading my CPU to 100%. The screen is blanked, the fan is roaring. I touch the machine and CPU usage stops. I see that everything is swapping in slowly. ps aux shows: seife@strolchi:~> ps aux|grep etwork seife 8345 0.9 0.8 30176 8560 ? S Oct31 11:36 knetworkmanager [kdeinit] root 9772 1.1 0.1 5308 1200 ?

NetworkManager logfile is 1.5GB. Last rotated yesterday. Will attach the output of "pmap" for the NM process and the logfile. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

I'll look into the memory leak and adding some guards in NM to not allow the infinite loops. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

If knm provides an invalid key, that's because it never asks me for the kwallet credentials and thus cannot know the correct key. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
