When using the release CAST 8.3.6, there have been cases where snapshot performance decreases.
In one case, this even led to a crash during the snapshot process.
There are multiple performance issues that may lead to a crash in the Central Base, the most important ones being:
- during the computation of the tree
- during some post steps of the snapshot consolidation
The issue depends on the application geometry, but generally if the application has a large number of analysis units, this behavior is likely to be observed, so the patch should be applied.
There is no impact on results, with the application of this patch; it is just a performance improvement patch.
To resolve this issue, apply the attached 836_snapshot_performance.sql file to the CAST local knowledge base and then rerun a snapshot. No need to rerun the analysis for this patch.
This issue has already been fixed in 8.3.7.
