VOLSNAP_OVERLAPPED_TABLE_ACCESS
The VOLSNAP_OVERLAPPED_TABLE_ACCESS bug check has a value of 0x0000012D. This indicates that volsnap tried to access a common table from two different threads which may result in table corruption and eventually corrupt the table.
VOLSNAP_OVERLAPPED_TABLE_ACCESS Parameters
None
Diagnostic focus
The failure indicates concurrent access to a Volsnap table that is expected to be serialized. Identify the two threads and the snapshot or volume operation each was performing, then inspect locking around table mutation. Repeated snapshot creation or deletion, backup filters, and teardown races are more relevant than general disk health.
