An APS-related task fails with an error like below:

Task name       Provisioning "context" for APS application BlackBerry 10
Last execution output   Internal error: SDK::Platform::blob Plesk::SaaS::SaaSManagerTasks_impl::taskExecuteWorkflow(const SDK::Platform::Properties&) : [APSC] system exception, ID ''  Unknown vendor minor code id (0), minor code = 0, completed = NO


The issue is probably caused by APS-15464, which was fixed in OA 5.5.5.

The cause is that during task execution DB connection times out while APSC transaction is still running, the connection is killed and the corresponding transaction is rolled back.


Please uodate to version higher than or 5.5.5.

To workaround update the following parameter in /usr/local/pem/etc/Kernel.conf file on POA Management node to higher values:


Recommended values for both are 1200, but it could vary depending on the task.

After the change, restart pem service on POA Management Node and re-run the task.
