    Lync Server 2013

Symptoms

Consider the following scenario:

  • Many user activities occur in a server pool in a Microsoft Lync Server 2013 environment.
  • The back-end server of the front-end server pool is running Microsoft SQL Server.
  • The back-end server is in full recovery mode.
  • Database mirroring is enabled on the back-end server.

In this situation, the transaction log for the user services database reaches maximum capacity. Therefore, you cannot start the front-end server, and the following is logged in an event log:

Also, you receive the following error:

SQL_9002_severity_17                                           sql_err
# The log file for database '%.*ls' is full. Back up the
# transaction log for the database to free up some log space.
# as an HRESULT: Severity: SUCCESS (0), FACILITY_NULL (0x0), Code 0x232a
# for decimal 9002 / hex 0x232a

Note

Run the DBCC SQLPERF (LOGSPACE) query to check the size and current capacity of all transaction logs on the back-end server.

Workaround

To work around this issue, truncate the transaction logs that reach maximum capacity by performing a SQL Server backup on them. This reduces the file size of the transaction logs.
