Hello,

I get this exception whenever I try to add a web part (actually it is one of
OSIsoft's RtWebParts package) to a apge

at

Microsoft.Office.Server.Administration.SqlSessionStateResolver.System.Web.IP

artitionResolver.ResolvePartition(Object key)

at System.Web.PartitionManager.GetPartition(IPartitionResolver

partitionResolver, String id)

at System.Web.SessionState.SqlSessionStateStore.GetConnection(String id,
Boolean& usePooling)

at

System.Web.SessionState.SqlSessionStateStore.SetAndReleaseItemExclusive(Http

Context context, String id, SessionStateStoreData item, Object lockId,
Boolean newItem)

at System.Web.SessionState.SessionStateModule.OnReleaseState(Object

source, EventArgs eventArgs)

at

System.Web.HttpApplication.SyncEventExecutionStep.System.Web.HttpApplication

.IExecutionStep.Execute()

at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean&

completedSynchronously)

All the other web parts are working fine. Any ideas as to what may be
causing this?

Thanks in advance!
