[Bug 436196] New: knetworkmanager enters infinite loop, unresponsive, loads CPU to max
https://bugzilla.novell.com/show_bug.cgi?id=436196 Summary: knetworkmanager enters infinite loop, unresponsive, loads CPU to max Product: openSUSE 11.0 Version: Final Platform: i686 OS/Version: Other Status: NEW Severity: Major Priority: P5 - None Component: KDE4 Workspace AssignedTo: kde-maintainers@suse.de ReportedBy: lmb@novell.com QAContact: qa@suse.de Found By: Development On 11.0 with all updates applied, I observe knetwork manager going into an infinite loop, using all free CPU time and heating up the CPU & draining the battery: It's stuck on: gettimeofday({1224174914, 8900}, NULL) = 0 poll([{fd=9, events=POLLIN, revents=POLLIN}], 1, 9398) = 1 gettimeofday({1224174914, 8981}, NULL) = 0 poll([{fd=9, events=POLLIN, revents=POLLIN}], 1, 9398) = 1 gettimeofday({1224174914, 9063}, NULL) = 0 .. lsof shows: knetworkm 8146 lmb 9u unix 0xcc879ac0 0t0 3344826 socket It is also the only process which appears to be connected to this socket, which explains the tight loop - apparently it is not able to handle that that socket was closed from the other end. A possible work-around is to kill knetworkmanager, which of course means all network connections get dropped briefly, and restart it. -- 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.

Does the issue still appear with 11.1? Is there an easy was to reproduce it? -- 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.

There wasn't really a way to reproduce, it would silently fail in the background eventually during normal operation. -- 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.
