Dear Vlad,

Did you mean gfix –validate ? Yes I tried it, and there is no errors.

Here is my memory test with dd command – the result of md5 is all same and no errors found :


About running DDL, yes.. I actively alter table as is needed. Is this forbidden on live database ?

Do you have a complete guide for database maintenance? and what shouldn’t and should do ?

Your database still get corrupted. gbak reads whole db therefore it detect corruption. But gbak is nor a reason of corruption, nor
a correct tool for diagnosis (gfix is). I ask you again to check RAM on server machine. One more question - does you run DDL
statements such as ALTER TABLE on live database ?
