Sometimes "shutdown in progress" after gbak restore since 3.0.11 (Classic)
Since we are using Firebird 3.0.11 some of our customers (about 1%) report a problem with gbak restore. The output then ends with:
gbak:finishing, closing, and going home gbak:adjusting the ONLINE and FORCED WRITES flags [FireDAC][Phys][FB]database D:\DATA\DATABASE.FDB shutdown in progress IProvider::attachDatabase failed when loading mapping cache unknown ISC error 336330835
This might be caused by https://github.com/FirebirdSQL/firebird/pull/7233
There is no shutdown in progress, it just thinks it is?
In our tools we delete the restored fdb afterwards in case of a problem, so we don't have a database to analyze. If the customer repeats the backup+restore, it runs without a problem. We are not able to reproduce the problem.
Windows, Delphi application, scheduled backup+restore under system account, Firebird Classic, svcmgr.
We switched most customers who experienced the problem from Classic to SuperServer (still 3.0.11). So far the problem has not occurred with SuperServer.
This problem exists also in 3.0.13.33818. Previously we reverted customers to 3.0.5, but with the security issue that is no longer possible. Today we captured a database after the restore, and it turned out to be fine. Could it be a timing issue, that we should wait a few seconds after the restore before performing other actions on the database?
