Microsoft Hotfixes Windows 7 Memory Leak

Consumers using Windows 7 and Windows Server 2008 R2 may experience a sudden crash of the operating system for no apparent reason. The system failure is accompanied by the infamous "Blue Screen of Death" containing the "STOP: 0x0000000A" error code. Microsoft was alerted to the problem, and has posted an explanation on the Microsoft support website.

According to the company, the actual error reads "STOP: 0x0000000A (parameter1, parameter2, parameter3, parameter4); IRQL_NOT_LESS_OR_EQUAL." Microsoft added that users will observe that the four parameters in the Stop error message may vary, depending on the configuration of the PC. The Redmond company also stated that not all "STOP: 0x0000000A" error messages are caused by this particular issue.

"This issue occurs because Power Manager opens an Advanced local procedure call (ALPC) port," the company explains. "However, Power Manager closes another port instead of closing the ALPC port. Every time that a power request is made, a memory leak occurs. When the leaked memory usage accumulates to a certain level, the computer crashes."

Windows 7 and Windows Server 2008 R2 consumers can obtain a hotfix for the problem by heading here.

    Little known fact: "0x0000000A" is actually "hammer time" in hex.

    lol, it closes ANOTHER port?? wouldn't that be a bigger concern?

    does it close the port on another computer? like "its ok dude, I'll save you from a memory leak, I'll take one for the team."

    It's an ALPC port, are you thinking of regular data ports or something? It would take an exceptionally large amount of time (or an insanely high amount of power requests) for this to show up in standard use, since each ALPC port takes approximately 4KB of memory. Assuming the port never closes, and assuming new ones are opened at (the default) of one every 30 minutes, it would take 6 days straight for 1MB of memory to leak, and it would take almost 40 years (straight) for the system to bluescreen because of it, under normal circumstances.

    I'm not saying this isn't an issue, but is an extreme edge-case scenario really worth making an entire news posting for? It's just another bug fix that would never have shown up in standard testing - I expect this only even manifests itself if you have software installed that polls power status far often than normal is healthy.
