I have 2 instances of opennms

Instance one (main):

OpenNMS.Eventd         : running
OpenNMS.Trapd          : running
OpenNMS.Queued         : running
OpenNMS.Actiond        : running
OpenNMS.Notifd         : running
OpenNMS.Scriptd        : running
OpenNMS.Rtcd           : running
OpenNMS.Pollerd        : running
OpenNMS.PollerBackEnd  : running
OpenNMS.EnhancedLinkd  : running
OpenNMS.Ticketer       : running
OpenNMS.Collectd       : running
OpenNMS.Discovery      : running
OpenNMS.Vacuumd        : running
OpenNMS.EventTranslator: running
OpenNMS.PassiveStatusd : running
OpenNMS.Statsd         : running
OpenNMS.Provisiond     : running
OpenNMS.Reportd        : running
OpenNMS.Bsmd           : running
OpenNMS.Alarmd         : running
OpenNMS.Ackd           : running
OpenNMS.JettyServer    : running
opennms is running

 

Instance two (webgui):

OpenNMS.Eventd         : running
OpenNMS.JettyServer    : running
opennms is running

 

When on instance two I add a new Requisition and some node and then do the synchronization and then “Refresh Requisition from Server” I get the error “Cannot retrieve the deployed statistics for requisition tomektes3. Check the OpenNMS logs for more details, or try again later.”, and the changes are unsynchronized.

Only one log wile that changes in this action is web.log

But the errors are not clear for me, what please help what can cause that.
