KdoLib 4025 Cannot Seize Semaphore It was Previously Locked

Issue

The Remote Synchronization Agent (RSA) is reporting an error message similar to the foillowing, and fails to synchronize:

[4025] KdoLib: Cannot seize semaphore '<BatchClassName>' (1). It was previously locked by '<OtherBatchClassName>' LockID={82ca65e1-d71c-496c-b7c4-a14c1eb87889}

 

Solution

This can be resolved on the Remote Site and running the following SQL commands:

"SELECT * from acsystem.dbo.xlock where abandoned = 1"

This command will allow you to determine if there are abandoned locks that need to be removed.

 

To remove the abandoned locks, run the following command:

"DELETE from acsystem.dbo.xlock where abandoned = 1"

 

Please see link to SQL EZ Query Utility which allows you to run SQL queries without the need for the SA password:
