.Net Runtime 2.0 crash after migrating from TC 7.5 to 8.7

Just wondering if anyone have seen something like this, After migrating the tested application crashes after running for an hour or so.



I see to system events:

Event ID: 1023

.Net Runtime version 2.05727.3053 - Fatal Execution Engine Error (7A097706) (80131506)



Event ID:1000

Faulting application <appname>.exe, version 0.80.759.0, stamp 50353ce1, faulting module mscorwks.dll, version 2.0.50727.3053, stamp 4889dc18, debug? 0, fault address 0x00123b4e.





I tried upgrating the 2.0 runtime from SP1 to SP2 but no improvement. things fo smooth under TC 7.5.



any ideas?

Thanks.
