Major - P3 Description
SERVER-23705 added code to enable the SeIncreaseWorkingSetPrivilege privilege for the mongod process on Windows.
If the server is running a locked down configuration, mongod is denied the privilege grant and the following warning is logged to stdout only during startup:
2020-03-26T16:03:35.664+1100 W - [main] Failed to adjust token privilege for privilege 'SeIncreaseWorkingSetPrivilege'
|
The log message can be easily missed, and if encryption at rest is in use the following fassert() can be easily hit after 10's of databases are loaded:
2020-03-18T07:32:00.387+0800 F - [conn301] Failed to SetProcessWorkingSetSizeEx: A required privilege is not held by the client.
|
2020-03-18T07:32:00.387+0800 F - [conn301] Fatal Assertion 40286 at src\mongo\base\secure_allocator.cpp 154
|
It would be good to log a startup warning that the required privilege is not available for use, so that the Windows system configuration can be corrected.
