Symptoms
Assume that you use Microsoft SQL Server 2014. When you run an online index build/switch partition with the option ABORT_AFTER_WAIT=BLOCKERS and parallel queries at the same time, a system assertion occurs and dump files are generated. Additionally, you receive the following errors:
<Date><Time> spid# Error: 1203, Severity: 20, State: 1.<Date><Time> spid# Process ID # attempted to unlock a resource it does not own: OBJECT: 9:245575913:0 . Retry the transaction, because this error may be caused by a timing condition. If the problem persists, contact the database administrator.……<Date><Time> spid# Exception occurred in destructor of RowsetNewSS 0x00000004C468A7C0. This error may indicate a problem related to releasing pre-allocated disk blocks used during bulk-insert operations. Restart the server to resolve this problem.<Date><Time> spid# Using 'dbghelp.dll' version '4.0.5'<Date><Time> spid# **Dump thread - spid = 92, EC = 0x00000004C3B98580<Date><Time> spid# ***Stack Dump being sent to <PathName>\<FileName>.txt
Note You can repro the issue by using the following commands:
ALTER INDEX ALL ON <TableName> REBUILD WITH ( ONLINE = ON ( WAIT_AT_LOW_PRIORITY ( MAX_DURATION = 0 MINUTES, ABORT_AFTER_WAIT = BLOCKERS ) ))
