Subject: [PATCH] Ticket 49402 - Adding a database entry with the same database
|
|
|
40cd75 |
name that was deleted hangs server at shutdown
|
|
|
40cd75 |
|
|
|

Bug Description: At shutdown, after a backend was deleted, which also had a import
|
|
|
40cd75 |
task run, the server hangs at shutdown. The issue is that the
|
|
|
40cd75 |
import task destructor used the ldbm inst struct to see if it was
|
|
|
40cd75 |
busy, but the inst was freed and the destructor was checking invalid
|
|
|
40cd75 |
memory which caused a false positive on the "busy" check.
|
|
|
40cd75 |
|
|
|
40cd75 |
Fix Description: Do not check if the instance is busy to tell if it's okay to remove
|
|
|
40cd75 |
the task, instead just check the task's state.
