Possible root cause for AppFabric Error Code ERRCAdmin025

  • Článek

While trying to start AppFabric Cluster with PowerShell cmdlet Start-CacheCluster, I receive the message below:

Start-CacheCluster : Error occurred while performing the operation :ErrorCode<ERRCAdmin025>:SubStatus<ES0001>:Time-out occurred in starting thecluster.At line:1 char:1+ Start-CacheCluster+ ~~~~~~~~~~~~~~~~~~    + CategoryInfo          : NotSpecified: (:) [Start-CacheCluster], DataCach   eException    + FullyQualifiedErrorId : ERRCAdmin025,Microsoft.ApplicationServer.Caching   .Commands.StartCacheClusterCommand

According to the AppFabric Error Code reference (https://msdn.microsoft.com/en-us/library/ff921008(v=azure.10).aspx), this is a Cache Administration timeout.  

Maybe there was so some permission issue with the DB. So I switched to using XML configuration with no luck. So what is really causing this? Another great place to look is the AppFabric Event logging located in "Application and Service Logs -> Microsoft -> Windows -> Application server - system services -> Admin"

 

In there one of the top error is ErrorCode<ERRCMS0011>:SubStatus<ES0001>:The host cache data size specified must be less than total physical memory.That is! Earlier I forgot that I had decreased the size of our physical drive on the AppFabric Server. Reducing the cache size setting (less than the physical memory size)in the cluster configuration solved the issue.
