原因
There could be some conflict with the cache-settings-overrides.properties for the upgraded Confluence.
ソリューション
Option 1
Verify if the cache-settings-overrides.properties file contains the below class :
cache.maxEntriesLocalHeap.com.atlassian.confluence.plugin.CachingPluginStateStore=2 If the above class is present in the cache-settings-overrides.properties file, update the above record to the below class and restart the instance as part of the workaround mentioned in the Bug - CONFSERVER-94958
cache.maxEntriesLocalHeap.com.atlassian.confluence.plugin.CachingPluginPersistentStateStore =2
オプション 2
Delete the cache-settings-overrides.properties file and restart the instance :
<home-directory>/shared-home/config/cache-settings-overrides.propertiesif you run Confluence on a single server.- Confluence をクラスターで実行している場合は
<shared-home>/config/cache-settings-overrides.properties
Note - The cache-settings-overrides.properties file stores the changes to the default cache size configurations from the UI under the General Configuration > Cache Management screen. Deleting this file changes the cache size configurations to default values in place of the custom values updated from the UI.
