Server crashes while switching to the shadow if the disk I/O fault happens while flushing the cache

Created: 20/Jun/12 06:47 PM   Updated: 13/Jul/15 04:25 AM
Component/s: Engine
Affects Version/s: 3.0 Initial, 2.5.0, 2.5.1
Fix Version/s: 2.5.2, 3.0 Alpha 1

QA Status: Cannot be tested

 Description  « Hide
This happens only if there are not active attachments at this point, e.g.:

- SS and FW=OFF: last user disconnects from the database
- CS and FW=OFF: any user disconnects from the database
- any arch and FW: the server is shutting down with active transactions

Unfortunately, some code parts attempt to access the NULL attachment pointer regardless.
