Why is the extended formula queue backing up?


We have quite a lot of rows in the extended formula queue that started to back up since Aug 29. At one point, we had over 900K in the queue and the process server is processing it pretty slowly. As of Sep 8, the system is still processing the queue. We are adding daily on average over 125K rows to the EF_QUEUE table.

We tried starting and stopping the Extended Formula Agent and Formula Recalc Agent and tried rebooting the process servers. We swapped the agents to run on different servers. We also ran the segment shrink on the EF_QUEUE table and gathered statistics. It is still extremely slow. We still have over 500K in the queue.

In parallel, we did open the platform logging on the extended formula activity and cache building, and we are working to identify the processes that can be fixed to reduce the multiple calls to the Extended Formula Agent queue. Do you have any recommendations to speed up the process to clear the extended formula queue?

Review the following two APARs. They may need to be applied to your environment to address this issue: (1) Platform: APAR IV87030. (2) Application: APAR IV87104.
