BPC Optimization Server Time Out error message

We’re using BPC 7.5 MS and on patch level 111.02

There’s two front-end servers and one back-end.

When completing a full optimization with compression on an application we immediately get the optimization popup screen with no processing information only a “Server Time Out” error message.

Optimization was taking a long to time run and sometimes timed out.  To try and resolve this issue we have just updated indexes and statistics and during our test in production we now receive the “Server Time Out” error message immediately. However, the records from tbl.Factwb and tbl.Fac2 did move to the tbl.Fact.

Our development environment test ran fine.

Any suggestions?

Thanks.
