prosody crashed - seems related to external auth script

[Jamie McClelland]

The output and behavior seems identical to this bug report:

​https://issues.prosody.im/1370

I restarted prosody and now it is working. Not sure if this will be a recurring problem.

Specifically, the error is:

Crashed again with the same error. There seems to be something wrong with the vesion of prosody we upgraded to and external auth. I restarted prosody and we are back up again.

[Jamie McClelland]

I've just updated our mod_external_auth module with ​the latest version. Maybe that will help.

[Jamie McClelland]

So far so good, I'm cautiously optimistic that the upgrade of the external auth script solved the problem. (and may have solved #11836 to boot).
