In a multinode setup, i am experiencing sync issues with one node. (all my nodes are Zabbix 1.8.5, latest revision)

Everything syncs fine except the events. The logs also show the syncing process being executed without error.
For clarity sake: there are NO connection issues between master and slave node.

The slave node reports an activated trigger and shows the actions next to it, but when i go to the masternode the event is either not there or the status is UNKNOWN instead of PROBLEM
Everything else syncs fine. So graphs, config changes, audit log, ...

Here's a line of the logfile: as you can see the events are being sent with datalen 4149.

28949:20110729:105439.111 NODE 4: Sending events of node 4 to node 1 datalen 4149

And i seem to receive them at masters end:

19037:20110729:105439.130 NODE 1: Received events from node 4 for node 4 datalen 4149

I've added two prntscreens where you can see the latest events for one host on master and slave.
