Firebird can be also involved in the problem?

Perodically we have corrupted databases on linux (85% wrong page
type). And this cannot be reproduced for ages. Currently we are
running FB 2.5.8 on 4.1.12 kernel.


Is 'forced writes' set for you DB?



In that case fsync should not affect your databases, as far as I 
understand with O_SYNC open flag it's just no op.
