EventLog Service

Hi There,
I am troubled with the following:
On my Windows Nt Server 4.0 SP6a the EventLog service automatically stops (EventID: 6006) and starts (EventID: 6005). After a period of 5-30 miutes the service again stops and then starts. Who knows whatis going on? I can not find the problem/cause myself.

(If the server was rebooting because of an abnormal shutdown “EventID: 6008” is shown in the log. But this not the case…)
