我们有一个在.Net 4上运行的混合模式汇编应用程序(MFC + WinForms),Windows 2008 R2在一个线程上不断使用100%cpu.
使用ProcessExplorer,我们在忙线程上看到以下堆栈.我们还可以看到另外10个线程只使用0.01%的CPU运行clr.dll!StrongNameSignatureVerification.
旋转线程不会阻止应用程序的其余部分运行,但会浪费CPU时间.
繁忙线程的堆栈跟踪如下:
ntoskrnl.exe!IoAcquireRemoveLockEx+0xe7
ntoskrnl.exe!memset+0x22a
ntoskrnl.exe!KeWaitForSingleObject+0x2cb
ntoskrnl.exe!KeDetachProcess+0x120d
ntoskrnl.exe!PsReturnProcessNonPagedPoolQuota+0x3a3
ntoskrnl.exe!CcSetDirtyPinnedData+0x433

clr.dll!StrongNameSignatureVerification+0x164d9
ntdll.dll!RtlCreateUserProcess+0x8c
ntdll.dll!RtlCreateProcessParameters+0x4e
我能找到的唯一类似帐户就是这个问题:clr.sll!StrongNameSignature验证CPU耗尽虽然线程似乎已经冷了.
我们不签署我们的程序集并且愿意信任它们,有没有办法完全禁用强名称验证？
