description |
I had a kernel problem with one of my high availability VMs. This was not the first occurence of the problem, it seems to appear every now and then.
The VM froze because of the Kernel bug appended as a text file. I had to hard reset it.
I am running Ubuntu 14.04.2 Kernel 3.16.0-34-generic with libapache2-mod-apparmor 2.8.95~2430-0ubuntu5.1 and apache 2.4.7-1ubuntu4.4 (mpm_prefork).
Unfortunately I am unable to reproduce the bug at will. This is a serious problem for high availability VMs.
Looking at the trace, I assume this is a bug in AppArmor. |
