Sometimes escalations don't stop mailing even tho the problems have been solved and zabbix doesn't show any problems again.

Steps to reproduce this problem:

• Trigger a problem
• After the first notification, disable the action
• Let the trigger return to it's OK state

The escalations are still in the escalations table in MySQL and will continue to send an email every hour. I usually disable actions when i expect a very large flood of notification (for example, when there is a DDoS going on) and i'm monitoring the dashboard anyway.

Workaround: Empty the escalation table in MySQL
