Error 3646



Message text

FATAL Error: Asynchronous logging server is stopped. You may have to terminate the user connections which may be hanging.


If the asynchronous logging service (ALS) process gets an infected stack trace, the process stops. The user connections that are waiting to be served by the ALS process may be hanging. Data modification activities are not allowed in the database. Error 3646 is raised.


Kill the user connections. If the connections are not killed, restart Adaptive Server, which will roll back the incomplete database transactions. Please contact Sybase Technical Support to report this problem.
