After an uptime of more than 2 days without any problem, I once again had t= wo killed processes yesterday evening (while building GHC, the Haskell compile= r), and then this morning while trying a big rsync, an "skb alloc failed" loop happened.

After a reboot, the rsync finished really quickly (can't estimate at which speed, but many MB/s) --=20 You are receiving this mail because: You are on the CC list for the bug.=
