Unable to start log writer thread.
Adaptive Server attempted to start a process to handle writing the log for the asynchronous logging service (ALS). This attempt failed. For more info on ALS, refer to the Performance and Tuning: Locking section “Asynchronous log service.”
Adaptive Server uses a process slot for the thread. Check to verify that the number of user connections is configured sufficiently high to allow for this. Increasing the number of user connections can help to resolve this issue.
If the 3643 error persists after configuration changes, it may be necessary to gather a configurable shared memory dump (CSMD). See the section “Configuring a shared memory dump on conditions” in the most recent version of the Troubleshooting And Disaster Recovery guide.
