hobbitd_channel uses 99% cpu

Hi,

I'm running xymon-4.3.0-beta1 on a CentOS 5.3 system. For quite a while xymon has been running smoothly. However, lately hobbitd_channel has been using 99% of the cpu. Sometimes there are two hobbitd_channels running, each using 49% of the cpu. Is there an ipc channel or shared memory that is somehow stuck or corrupted?

ipcs shows nothing when xymon is stopped, and shows 9 memory segments an 9 semaphore arrays when xymon is running.

What is going on? Did I mis-configure something? Is there a way to watch it or debug the problem?

Thanks,

Wendell
