Description
The MUST_SUCCEED_POOL_EMPTY bug check has a value of 0x00000041. This indicates that a kernel-mode thread has requested too much must-succeed pool.
Important
This article is for programmers. If you're a customer who has received a blue screen error code while using your computer, see Troubleshoot blue screen errors.
Cause
No driver is permitted to request must-succeed pool.
If a must-succeed request cannot be filled, this bug check is issued.
Resolution
Replace or rewrite the driver which is making the request. A driver should not request must-succeed pool. Instead, it should ask for normal pool and gracefully handle the scenario where the pool is temporarily empty.
The kb (Display Stack Backtrace) command will show the driver that caused the error.
Additionally, it is possible that a second component has depleted the must-succeed pool. To determine if this is the case, first use the kb command. Then use !vm 1 to display total pool usage, !poolused 2 to display per-tag nonpaged pool usage, and !poolused 4 to display per-tag paged pool usage. The component associated with the tag using the most pool is probably the source of the problem.
