After migration to version 1.8.8 began noticing intermittent incorrect display of flip-flops.
The logic of monitoring:
Hosts work in zabbix-proxy. Monitor the status of hosts by means of ladders. Pitfall traps is on the zabbix-proxy. All items / triggers are registered on the hosts locally, without templates (templates initially connected, and then detached from the persistence of the data).

Description of the file attachments and problems:
1. Monitoring-Triggers:
operating window «Monitoring» -> «Triggers», which can be seen, the trigger has the status of «PROBLEM», though the port is already «UP (1) '(display in the trigger occurs through« Value mapped »). Time the trigger in 11:11:00.

2. Latest_data - PortStaus:
window «Monitoring» -> «Latest data», the port is "administrative" and "operational." It is evident that both elements were 11:11:14 value "1", ie ports have moved into a state of «UP».

3. Latest_data - History
History shows the values ??for the "operational" state of the port. We see that in 11:11:00 port moved to the state «Down» (data item has a value of "0"), which corresponds to the time of the trigger, and then, at 11:11:14, a data item has the value "1".
At 11:11:00 and 11:11:14 element that collects "administrative" state of the port receiving the same data "0" and "1" respectively, which indicates proper operation handler traps and pass values ??to the proxy on the main server.

4. Item_config
given the current configuration of the element that collects "operational" state of the port «E5».

5. Trigger_config - ifOperStatus:
description of the configuration of the trigger for the "operational" state of the port «E5», for which there is an incorrect indication. Here comment from the trigger is removed.

6. Trigger_config - ifAdminStatus (dep):
description of the configuration of the trigger for "administrative" status of the port «E5», from which the dependence of the trigger for the "operational" state of the port.

7. MySQL - ItemStatus:
current state of the element in a MySQL database for "operational" state of the port «E5», after he obtained a value of "1": field «lastvalue» = 1.

8. MySQL - TiggerStatus:
current state of the trigger in a MySQL database for "operational" state of the port «E5», after the element was set to "1": field «value» = 1.

WHY?? After all, the trigger condition (see attachment "5. Trigger_config - ifOperStatus») is satisfied! And it shows in the screenshots:
"1. Monitoring-Triggers », in the line:" Interface E5 (**********): Up (1) »
"2. Latest_data - PortStaus », the last value of" 1 "
"3. Latest_data - History », the last value of" 1 "

9. MySQL - history_uint:
in any case given the history of the state for a gathering "operational" state of the port «E5».

PS: If you disable the dependency for a trigger that has already worked in my case, "Interface E5 (**********): Up (1)", the indication alarm message continues.
PSS: in file «triggers.inc.php» I made small changes that would patch up malfunctioning macro

{ITEM.VALUE} for WEB interface using «Valuemapped» (see ZBX-3423).
PSSS: while describing the problem, there was a decline and recovery of more than one port, but only with other equipment, and without the administrative block, as described here. Port fell to 3 minutes (in the situation described here for 14sek), and then got up and moved to the trigger status «OK». Configuration items and triggers for this equipment are identical to those described here above.
