Unified Map displays the following error - "ERROR. The server returned an error retrieving map data (error code: CMDBUM-500-001)" when a large number of references are shown on the map Description The Unified Map displays the following error - "ERROR. The server returned an error retrieving map data (error code: CMDBUM-500-001)". This is a known error when when a large number of references are shown on the map causing the total node count to exceed the value set in the system property which declares the max number of nodes. The error is caused by not taking into account the number of references pulled into the map and causes the total number of nodes to exceed the maximum.

Steps to Reproduce

Open CMDB workspace

Open the Unified Map page for the CI whose map has a very large number of references

Upon map load, the error will be displayed.

Workaround The current workaround is to increase the limit on the Glide Property (sn_cmdb_ws.node.map.max.edge.count) which defines the maximum node count. The value should be larger than the total node count for the map that is displaying the error. Please note that this value is global for all maps shown, which will result in potentially larger maps being shown in the map.
