"Crash" would be the wrong term here. Sorry.
The application did hang and not respond anymore.
It did receive the SIGINT (ctrl+c) and showed the message "
[main.cpp:43] Shutting down..."
but I does not shutdown clean, it does not do anything else but showing
this message.
I've tried to clean up the filesystem to free inodes. So I can't
reproduce it right now.
The last error log I've got was from redis:
"ERROR: MISCONF Redis is configured to save RDB snapshots, but is
currently not able to persist on disk. Commands that may modify the data
set are disabled. Please check Redis logs for details about the error."
The problem was not that the file system has run out of space, but that
there are no free inodes.
I've got plenty of diskspace (~25GB) but had 0 free inodes (5.5M used,
100%).
Since it's not possible to increase the inode count I would have to
reformat the root partition.

I will move the data dir to another partition and see how long that
lasts (right now 30M free inodes). Thanks!
Cheers
