Server - Trapper item with regexp trigger in multiple event generation

Hello!

Steps to reproduce:

1. Create a Zabbix trapper item with text type of information.
2. Create two triggers for this item with multiple event generation, no OK event generation option and different severity:

   {<host>:<item>.regexp(NORMAL)}=1

   {<host>:<item>.regexp(MAJOR)}=1

3. Send the values via zabbix_sender with timestamps, for example:

   zabbix_sender -z 127.0.0.1 -i /tmp/test.values -T

   Sample contents of the file:

   <host> <item> 1509466739 "NORMAL"
   <host> <item> 1509466739 "MAJOR"

Result:

When sending the values for the first time - Zabbix will indeed create two different severity events. When sending more with the same timestamp from the same file - Zabbix will use severity from the last value of previously sent value pair.

Please refer to the screenshot for visual representation.

Expected:

The events should be generated with the corresponding severity as well as regular expression filtering should be processed correctly.

Please let me know if you would require additional information.

Regards,
Oleg
