[Bug 723616] New: Clicfs stalls completely on low memory
https://bugzilla.novell.com/show_bug.cgi?id=723616 https://bugzilla.novell.com/show_bug.cgi?id=723616#c0 Summary: Clicfs stalls completely on low memory Classification: openSUSE Product: openSUSE 12.1 Version: Factory Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Basesystem AssignedTo: mszeredi@novell.com ReportedBy: coolo@suse.com QAContact: qa@suse.de Found By: --- Blocker: --- Possibly there is no fix for this - or it's a feature request, but I file it anyway. If clicfs runs into low memory situation (faked by ulimit -v), it happens that I get fuse: failed to allocate request and after that nothing works anymore. Neither the clicfs process nor the file system see any action or error in this situation. Everything stays in D. In the code there is simply a return, but I have not really an idea what happens without reply - nor what clicfs can do about it. Preferably fuse would call some kind of emergency function and return an error to the filesystem. -- 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.

I think there are ways to prevent that too, if running privileged. -- 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.
