expireover takes long time

[Ulrich Schmid]

Hi

After a kernel upgrade from 2.4.25 to 2.6.15 the expireover run needs
much more time. The news server is running Debian Linux (sarge) and INN
uses buffindexed overview method.
I see this behavour with INN 2.4.1 and INN 2.4.3.

Any ideas what happens and how to reduce the expireover time with the
2.6 kernel?

Thanks and regards
Ulrich
