https://community.esri.com/t5/arcgis-enterprise-ideas/limit-server-memory-usage-for-toolboxes/idi-p/1673727 <P>Hello,</P><P>During our regular operations in Parcel Fabric. There is a few tools which if you do not have proper selections can attempt to run on the entire fabric. Specifically weighted LSA, this is fine if your fabric is a few hundred thousand parcels, ours is almost 2 million! When a weighted lsa is run without selection, it locks up the version, and then also starts a runaway train that will ramp the service up to 100 percent RAM usage. Depending on the version of Enterprise you are on, that will either crash the service and reboot, or just lock the service up and block the majority of the requests coming in for it and you have to manually restart.</P><P>I would ideally like some way to limit the amount of RAM that a process can use and give this a way to fail gracefully instead of either taking everything out or forcing a restart.</P><P>Thank You!</P> Wed, 17 Dec 2025 18:53:22 GMT SeanLyons 2025-12-17T18:53:22Z https://community.esri.com/t5/arcgis-enterprise-ideas/limit-server-memory-usage-for-toolboxes/idi-p/1673727 <P>Hello,</P><P>During our regular operations in Parcel Fabric.
