[Xymon] CONN status clear on only one host

Hello,

I am using xymon server on Centos 5.7 machine for monitoring 15 Centos machines. On every machine there is xymon client installed. Everything works fine, except on one machine host1 at domain1.com (Centos 6.0) conn status shows white face, but the message is Service conn on host1 at domain1.com is OK (up).

Also, if I try fping host1 at domain1.com, from the machine with xymon server, I get: host1 at domain1.com is alive.

All other services (cpu,memory,procs..) shows green face.

Thank you for your help
