LEI timeout problem

Hello,

We are using Lotus Domino R6.02CF2 on an ISeries (R5.2) System.

I have a special replication activity to sync the partdatabase with a copy
in the Domino System. (We use it for filling formulas with this
information. Just a DBLookUp and you can grab the information from the
copy.)

As the partdatabase is quiet lareg, (> 60000 items), this replication
takes very long (> 3h).
My problem is, that the lei is often starting the activity, but after ~2h,
I get an failure, indicating a timeout in the Notesdatabase, where I
replicate the partdatabase in.

I have already checked the Domino setting: Agent Manager max lotus script
execution time, but all seems ok.

Any ideas why this problem happens. (In the version 3.2a of the LEI Server
this problem did not occur.)
