node does not synchronize when there is incoming traffic
When there is incoming traffic to a node during synchronization it stucks in uncalibrated/wr-locked state (103), then after a timeout it goes to slave state (9) instead of wr-resp-calib-req (106).
Error can be reproduced by issuing following command from another
machine in the WR network.
$ ping -fi 0 192.168.1.20
The same behaviour was seen when many snmp get requests were done in the
same time.
