backup process (tar|xz -4, nice'd and ionice'd -c3) from ext4 on local
ATA disk to ext3 on external USB disk (USB-2.0 port on PCMCIA card).
Even though earlier system load was minimal, free memory was plenty, the
system now is unresponsive and is thrashing the disk, but the swapfile
is rarely touched.
I'm now having the same experience even though I replaced xz (which
needed ~50MB RAM) with gzip. Even though I feel the realtime root shell
is a bit more responsive than before, the OOM killer is out killing
small processes like syslog-ng and systemd-logind... The
ext4_inode_cache slab is taking almost all my memory (117MB). Please
advise!
interesting for you. It landed in -stable kernels recently as well if I
remember right...
