Lost asynchronous workitems


When the scheduler is restarted and the execution of the asynchronous tasks is lost, the pending tasks are not executed again.

Applies to

Bizagi Scheduler version 1.0 non-clustered


After the restart of the scheduler, the unexecuted asynchronous tasks are not re-executed.


The error is caused because the procedure which fixes the unexecuted tasks is configured for clustered environments.


We recommend upgrading your Bizagi Scheduler to version 2.0. For more information about how to upgrade, refer to https://help.bizagi.com/bpm-suite/en/index.html?scheduler2_0.htm.

Otherwise, as a workaround, configure the scheduler as a cluster with a single node adding the following keys in the BizAgi.Scheduler.Services.exe.config file located in C:\Bizagi\Projects\[ProjectName]\Scheduler folder.

<add key = "SchedulerClusterID" value = "1" />
<add key = "SchedulerClusterSize" value = "1" />
