to the next software release while the Unable to show "metadata-from": No such page "_space_variables"
continues handling calls.During an LSWU process, when the Standby SBC is in "Sync" state (which usually takes about 2 - 3 minutes), the new call data is queued on the Active SBC. Those calls are not marked as stable. Once the "Sync" is complete, the pending call data queue is moved from Active SBC to Standby SBC. Those calls are marked as stable. Therefore, check the callCountStatus when both Active and Standby SBCs complete the "Sync" state.
This page lists the average call rates and capacities for the following
