+.{kib} out of memory crashes on 1 GB {ecloud} {kib} instances using {elastic-sec} view
+[%collapsible]
+====
+
+*Details*
+
+{ecloud} deployments that use the smallest available {kib} instance size of 1 GB may crash due to out of memory errors when the Security UI is loaded. 
+
+*Impact* +
+
+The root cause is inefficient memory allocation, and this is exacerbated when the prebuilt security rules package is installed on the initial load of the {elastic-sec} UI.
+
+As a workaround, you can upgrade your deployment to 8.17.1 in which this issue has been resolved by https://github.com/elastic/kibana/pull/208869[#208869] and https://github.com/elastic/kibana/pull/208475[#208475].
