Event log doesn't overwrite as needed in SP4

Hello All,
After upgrading from SP3 to SP4 on several Windows 2000 PRO machines everything looked fine, but from time to time applications can't write to the event log.
When I try to view the application event log it appears to be empty. If I "clear all events" and re-start the service, the problem is fixed and applications can write to the event log. But it usually repeats itself after a few hours/days.

I could replicate this problem several times and it is very disturbing because I have many applications writing to the event log.
The application event log is set to "overwrite events as needed'.

Any ideas?

The event log is proparly configured - it just not working as it should.
The first link shows a way to clear the log using a script. I might use it if I won't find any other solution but I don't like it.

Try going back to SP3 on one machine and see if it still happens.  If it doesn't, reapply SP4 and hope it works OK.

It worked fine with SP3.
It happened on many machines including in a different company - I don't think re-applying will help.

There are a lot of bugs with SP4 so it might be worth just keeping on SP3 with latest patch's until SP4a/SP5 comes out.

That is always a good advice - always be one step behind with MS products.
However, I don't want to go back to SP3 because I would hate to test the MS uninstall utility.

I am also experiencing this same problem (event log not overwriting as needed) on W2K systems in the field.

You might want to try this SP4 hotfix. The hotfix claims to fix a problem with corrupt event log files when the log is full and wraps.
