miagos:~ $ uname -a Linux miagos 3.9.6-200.fc18.x86_64 #1 SMP Thu Jun 13 18:56:55 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
I have a reproducible issue, when my desktop Linux node stays online for more than ~24 hours and any attempt to
scp login, the node just freezes.. no response at all, keyboard, mouse, IP stack halted, no ping response etc.. all frozen and requires a hard reboot.
This only happens anytime after ~24 hours uptime; after a reboot there is no login issue.
After reboot, around ~24 hours later,
ssh will ask for my password and only after inputting correct password (attempting to spawn a shell) the machine locks up, a failed password re-asks as normal and an SSH session that does not open a terminal (strictly for Dynamic forwarding) works without lockup within the bug period.
Now I really want to know how to place the node in some type of DEBUG (Kernel or Openssh?) setting to get a clue as the logs (via
journalctl) doesn't display anything useful before lockup.
