Zabbix repeating eventids - 3.2.3

[Pedro.Almeida]

From time to time we get this:

  6649:20170118:102500.261 [Z3005] query failed: [1062] Duplicate entry '49' for key 'PRIMARY' [insert into events (eventid,source,object,objectid,clock,ns,value) values (49,3,0,16899,1484735100,74906971,0),(50,3,0,24486,1484735100,75280013,0),(51,3,0,26586,1484735100,75515360,0),(52,3,0,26901,1484735100,75670624,0),(53,3,0,27019,1484735100,75735364,1);

As if events restarte inserting at 1. This also occured on 3.0.x on this same instalattion.
If I restart the server process (sometimes a couple times) the problem disappears.
Where does zabbix gets its next eventid from? (it's not on the 'ids' table).
