    If you see RxExceptionFilter on the stack then the 2nd and 3rd parameters are the


6262
    exception record and context record. Do a .cxr on the 3rd parameter and then kb to


6363
    obtain a more informative stack trace.


6464
    The high 16 bits of the first parameter is the RDBSS BugCheck code, which is defined


6565
    as follows:


6666
     RDBSS_BUG_CHECK_CACHESUP  = 0xca550000,


6767
     RDBSS_BUG_CHECK_CLEANUP   = 0xc1ee0000,


6868
     RDBSS_BUG_CHECK_CLOSE     = 0xc10e0000,


6969
     RDBSS_BUG_CHECK_NTEXCEPT  = 0xbaad0000,
