Hi Martin, Then I guess it's a bug. Please try running a query over 44k, you'll get MAPI = monetdb@localhost:50000 ACTION= read_line. QUERY = select count(*) from plk100 WHERE c15 IN ('00501','00544','01001','01002','01003'.......... ERROR = Connection terminated Any query under 44k runs fine, so I'm assuming the limit is 64k (query + other packet data) Thanks. Dariusz. Martin Kersten wrote:

most probably yes --- at least there should be a proper error message in case the query is considered "too large". Could you please file a bug report via our bug tracker on SF? Please include detailed instaructions how to reporduce the problem; if possible, consider providing your full query, table schema and data.

Well, of course further analysis is required to locate the actual cause of the problem/bug ... Does the server survive, or does it crash? In either case, are there any message on the server console (or in the log(s) in case you're using merovingian)? Thanks! Stefan
Thanks. Dariusz.
