Has the main repository been updated with the patch or we must still use experimental?
please also collect the debugging information described in this thread and post it (together with container configuration, any special information about your setup, and output of pveversion -v) - it is vital for us to find out whether there are remaining issues in lxcfs.I stil have this sometimes....if i my brain doesn't fool me, this likely occurs only in containers migrated from OpenVZ (PVE3) ... I'll try to verify this
