Baseline sync error: Execution Timeout Expired
Keep getting the below error for link's baseline outgoing sync to AD. I have tried to restart IdB service but no improvement. I don't have DB Admin right as it is PROD env and Shared SQL cluster. Just wonder what can I do to troubleshoot it?
Synchronization job failed syncing 40800 changes on the 'AD Link' link from the locker to adapter with the reason Execution Timeout Expired. The timeout period elapsed prior to completion of the operation or the server is not responding.. Job ID: e6165705-b8bf-4e86-953e-c1394ae692c8 Duration: 00:16:54.3542205

Answer
Hi Huu,
Are you noticing SQL timeouts for any other operation? Does a service restart have any effect? Do you know what maintenance tasks are being performed on the database (see UNIFYBroker SQL Server Database Recommendations)?
No. TImeout only happens to Link Sync. I restarted the service several times but it did not help. The database is just new, I just installed IdB plus, ported the solution, did import and now sync-ing.
I will run maintenance tasks now but I doubt it will help
I ran the db maintenance task and tried to do manual baseline syncbut it is not running
It keeps queuing even though I kicked it off 25' ago
In the meanwhile, nothing else is running in IdB
Queuing a baseline synchronization job requires generating sync changes for all entities on both sides of the link, which again is a SQL-heavy operation. Do you know the hardware specifications of the SQL Server cluster or any of its configuration settings that might impact SQL performance? Do you know of any differences between how it's configured between this environment and the previous environment?
Feel free to re-open if there is a further update.
