A internal server error like "stack overflow" can cause the exception of "Validation of viewstate MAC faild"

The exception: Validation of viewsate MAC faild. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationkey and validation algorithm. AutoGenerate cannot be used in a cluster.

 

For this exception, it may not be caused by that what the excption descripted, I catched it before, that time it just caused by a internal server error-a stack overflow exception, so please note.
