I use a self compiled vdr 1.7.16 to get HD-TV functionality, but i think the bug is in the kernel near videobuf_read_start. I could not keep my system running by niceing vdr - so the oom-killer would kill it and free mem in case vdr has a memory leak. Additionally i would like to note that the machine is a Xen Dom0 host and runs some other domains - probably dvb buffer gets confused by the available memory? -- 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.

needed info provided with last comment/attachment.
No, the debug flag needs to be engaged prior the OOM (to see if there is a leak or not).
Another question: is it possible that broken hardware triggers this bug?
Everything is possible, but I doubt so. -- 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.
