BACnet server polling failure

[krh]

Are using the LM5 lite as a BACnet server and export KNX objects to BACnet.
When I poll from BACnet client towards the LM5 it often get no response. 
That device polls data every second. If I adjust so it polls only every minute the same happens. Sometime it gets data and sometimes not. We also have an another device on the same network acting the same towards LM5. Tried polling 15 sec, 1 minute on that device. Often it could work one minute and fail the another and comeback after 3-5 minutes. 
Unfortunately the device we are using is not able to use COV towards the LM5.
 
CPU, memory load and all seems normal and low. Same with KNX side, not much traffic and normal response in the webserver for the LM5. Reboot with no effect.
 
 
HW: LM5 Lite (i.MX6)

Please check with YABE if it works correct. What bacnet client do you use?

When using YABE it normally fails (device show up/network info) but sometimes work if we hit when it reply on request.
I am using a HMI from Exor, type Ex715.

Do you have bacnet client app or script installed?

Do you have bacnet client app or script installed?

Yes, bacnet client app (was testing it). How could i remove it if that is causing trouble?
Had also some event based scripting that i now just removed.

Yes uninstall it, server and client should not run on LM at the same time.

Yes uninstall it, server and client should not run on LM at the same time.

Uninstalled and now it works fine.
