We have a weekly job that takes a COPY.OUT from the "Live" database and
then does a COPY.IN to a development database in a separate
installation. I've noticed that in one instance, the ERRLOG is getting
a number of messages of the general form
"E_DM9063_LK_TABLE_MAXLOCKS Current logical lock ( 11 ) on resource
iihistogram in database test_cars_sol exceeds the specified maximum (
10 ). Escalating to table level lock"
(this also occurs on iidbdepends, iiqrytext,iirule and iitree (although
in that case the numbers are 51 and 50...)

The CBF parameter system_maxlocks is set to 10 on every installation,
and although there are differences in other parameters (the affected
installation is on a much smaller/less powerful machine) I can't see
any that I would expect to have an effect...

It's not really a problem as such - the job completes, and it runs over
the weekend so even if every escalation causes a delay it does not
prevent the refreshed database being available by Monday morning, but
it does puzzle me as to why it only occurs in this one case...

Hi Peter,
The process that copies the database ends up with an optimizedb and a
sysmod, so the answer is every week. - a lot of the messages referring
to iihistogram relate to the optimize. However this morning I ran
onother sysmod, followed by an optimizedb which generated no
messages...
