I have start testing Firebird 2.1 last week and stumbled in a possible bug:
whenever I select from one of the new monitoring virtual tables I receive
Statement failed, SQLCODE = -902
operating system directive open failed
In isql, the error is printed just after the headers. No records are
In the firebird.log I get this:
IvanAMD32 (Server) Tue Feb 5 23:52:36 2008
Cannot initialize the shared memory region
Tested with both beta(?) 2 and rc 1. OS is Ubuntu 7.10. Firebird is
SuperServer 126.96.36.19935 installed with the script provided in
the tar.gz package. Database was backed up and restored
properly. ODS version is 11.1. Problem only happens with
monitoring tables and everything else looks OK.
