Monitor instance bigip *.*.*.*:443 UP --> DOWN from gtmd (no reply from big3d: timed out)

Hi,

 

 

Both our GTM's are filling the logs with the following entries every few minutes.

 

 

Monitor instance bigip *.*.*.*:443 UP --> DOWN from gtmd (no reply from big3d: timed out)

 

 

SNMP_TRAP: VS test.co.uk-test-nat (ip:port=*.*.*.*:443) (Server BIG-IP_Pair) state change green --> red (VS test.co.uk-test-nat : Monitor bigip from gtmd : no reply from big3d: timed out)

 

 

Monitor instance bigip *.*.*.*:443 DOWN --> UP from 10.224.200.8 (UP)

 

 

SNMP_TRAP: VS test.co.uk-test-nat (ip:port=*.*.*.*:443) (Server BIG-IP_Pair) state change red --> green

 

 

This is happening every few minutes.

 

 

We have tow data centres with a GTM at each site which connect in to an LTM pair in an Active - Standby set up.

 

I'm only seeing these logs for at one data centre.

 

 

Any ideas why this would be happening.

 

 

 

Thanks
