Hobbit server itself not reporting most services

Hi,

For 2 weeks, on a hobbit server 4.2.0 there is a repeat critical error:

[...]
009-02-02 09:43:16 BOARDBUSY locked at 1, GETNCNT is 0, GETPID is 7386, 1
clients
2009-02-02 09:43:21 BOARDBUSY locked at 1, GETNCNT is 0, GETPID is 7386, 1
clients
[...]

So, the monitoring hangs at this time.

To avoid it, i restart hobbit service.

I read that someone suggests to delete hobbid.chk (corruped ?). I tried but
nothing changes...

Is there another way to correct it ? 

Thanks

Regards,
Nicolas
