Subject: [PATCH 2/5] Issue 49170 - sync plugin thread count not handled
|
|
|
74ca47 |
correctly
|
|
|
74ca47 |
|
|
|
74ca47 |
Bug Description: If sync repl connections get aborted the thread_count is
|
|
|
74ca47 |
not properly updated which leads to the server hanging
|
|
|
74ca47 |
on shutdown.
|
|
|
74ca47 |
|
|
|
74ca47 |
Fix Description: When connections get aborted we still need to shutdown
|
|
|
74ca47 |
the result thread cleanly: remove the req, update thread
|
|
|
74ca47 |
count, etc.
