We have trigger (icmpping) that stuck in problem state.
23.02.2016 05:07:21 - host was really not responding, after a while host started to respond, but the trigger didn't change status to OK.

Host is monitored by the proxy.

• - This is second time it happened. We had another host with same problem fixed with "unlink and clear" template, but we don't want to lose data this time.
