st=fail on gateway

[cayco]

Hi,

Why am I getting these:

Started!
0;0;3;0;9;read: 21-21-0 s=12,c=1,t=38,pt=4,l=4:5001
0;0;3;0;9;send: 0-0-21-21 s=11,c=1,t=0,pt=0,l=0,st=fail:
0;0;3;0;9;send: 0-0-20-20 s=0,c=1,t=0,pt=0,l=0,st=fail:
0;0;3;0;9;send: 0-0-21-21 s=10,c=1,t=1,pt=0,l=0,st=fail:
0;0;3;0;9;send: 0-0-21-21 s=12,c=1,t=38,pt=0,l=0,st=fail:
0;0;3;0;9;send: 0-0-20-20 s=1,c=1,t=38,pt=0,l=0,st=fail:
0;0;3;0;9;send: 0-0-21-21 s=13,c=1,t=23,pt=0,l=0,st=fail:    

It can read from sensors:

0;0;3;0;9;read: 21-21-0 s=12,c=1,t=38,pt=4,l=4:4979
MyMQTT/21/12/V_VOLTAGE
0;0;3;0;9;read: 21-21-0 s=12,c=1,t=38,pt=4,l=4:5001

I switched radios but the result's the same. I also experience some problems with sending commands by hand: http://forum.mysensors.org/topic/921/strange-value-being-sent-from-controller-using-mixed-temp-relay-node/33

Do you have any clue what could be wrong?
