Hi, We update our MonetDB databases using COPY INTO commands, we recently have started to get errors similar to the following error. GDKerror:!ERROR: GDKload: cannot read: name=13/52/135274, ext=theap, 56932 bytes missing. !OS: No such file or directory GDKload: cannot read: name=13/56/135610, ext=theap, 906 bytes missing. !OS: No such file or directory Deleting and recreating the tables and the schema haven't helped. If we create a new table with a table name not used in the past then we are able to use COPY INTO commands to update the new table. It is also possible to update the broken tables using 'INSERT INTO' commands. We see the problem only when we use COPY INTO commands. We use MonetDB Jan2014-SP1 release. We have 3 database nodes that 2 of them doesn't show this error. Any help much appreciated. We also don't know yet why we have started getting this error, any notes on how one can start getting this error would also be helpful. Mahmut Uludag
