We’ve identified an issue with the latest deployment that affected the performance of community smart apps, with the majority of the issues coming from scheduled executions. The update had an impact on the way that smartapps/devicetypes are loaded into memory and the net effect is that that they executed slower because of the increased load, which caused a higher frequency of app timeouts (an execution is canceled if it runs longer than 20 seconds). We’ve made tuning changes to the servers running the apps and the number of timed out executions is back down to average frequency.
