bitcoind crash

[genjix]

Today bitcoind locked up on my server and wasn't responding to errors.

Apart from saying 'bitcoin shouldn't crash', what kind of backup systems could exist to gracefully recover when Bitcoin locks up?

Not sure what can be done except calling an safety check hook which kills/restarts bitcoind. Ideally it'd be nice to run multiple nodes and switch between them freely (sharing the same wallets or having 'backup' nodes with a BTC store).

That is likely because of a deadlock issue, see:

You didn't mention your operating system.

Ubuntu. Even if there's a patch for this problem, it's good to have a backup for if Bitcoin does crash.

Ubuntu.

I've not used it, but perhaps Monit might be useful.  i.e., configure it to check the bitcoind process' health and then restart it if there's no response:

Are you OCing your CPU and/or GPU? If so, by what percentage? And what CPU/GPU?

  gjs278 shared a monit script to restart:

  Restart bitcoind automatically if it crashes or dies using Monit:

Also, plz enable core dumps. It is useful for know of the reasons of crash.
It can be done by creating this files:

Code:

$ cat /etc/sysctl.d/coredump_pattern.conf 
kernel.core_pattern = /tmp/core.%e.%t.%u.%g.%p

$ cat /etc/security/limits.d/coredump.conf 
* - core unlimited
