June 13, 2023 - Advisory: Increased Process Memory Usage

InterSystems has corrected a defect that causes increased process memory usage.

Specifically, the increased consumption of local process partition memory occurs when executing $Order,  $Query, or Merge on local variables.  While this will have no detrimental impact for most running environments, environments that support a large number of processes or closely limit Maximum Per-Process Memory could be impacted.  Some processes may experience <STORE> errors.

The defect exists in 2023.1.0.229.0 but it is reposted as 2023.1.0.235.1 with the fixes included, to expedite the correction without clients needing to wait for a maintenance release.

The corrections for this defect are identified as DP-423127 and DP-423237.  These will be included in all future versions.

The defect appears in versions 2022.2, 2022.3, and 2023.1 (build 229) of InterSystems IRIS®, InterSystems IRIS for Health™, and HealthShare® Health Connect.  If you are running one of these versions, we suggest upgrading to 2023.1 (build 235).

This correction is also available via Ad hoc distribution.
