Tons of empty e-mails

[jumashev]

I am confused because receiving tons of empty e-mails from Zabbix. I cannot find the reason and tried to mess up with disabling-enabling triggers or whole templates but it doesn't help

Has anybody reached such problem at 2.2.3 stable?

The only custom i have is debian updates template and percona monitor template, but after i disabled them the problem didnt dissapeared

The headers of the letter:

Interesting, but Zabbix doesn't show them at sent triggers or actions or anywhere..

So while post was moderated i have found the problem source by self

The trick is that ru locale has no default data for action "Autodiscovery".

I just followed the whole chain of MySQL data actions and so.. it was too simple.

After i changed the trigger settings, all went back to their places.

I hope my problem and it's simple solution will be useful for somebody.
