Redundancy errors

Redundancy errors

Hi all!
Today i was editing my project, trasfering it to primary server and then press "Reload project" via remote transport. Then i noticed that my clients (2 computers) start to switch between primary/secondary server. And again and again....cyclically.
I started diagnosis Viewer and save 2 files(1 for primary, 1 for secondary). Can you look at them and tell me something, in what direction I must look to solve the problem.
Before this redundancy worked normally, i've specially tested it before.
I have filtered diagnostic log only with "Zen" name of log connection
