dual identity client

Hi,

I'm running xymon client 4.3.0-beta2 on a host called TOTO, i also installed xymon server 4.3.0-beta2on TOTO. All my xymon clients report their statuses to TOTO and TATA (a host running xymon client 4.2.2/ and xymon server 4.3.0-beta2). Since I installed xymon server 4.3.0-beta2 on TOTO , TOTO's xymon client reports itselfs alternatively as "TOTO" and "TATA" . I searched very hardly what should be the reason. I can't find any "TATA" in the TOTO's xymon client directory.

Any idead ?
