Hey Jeff,

We actually are running into (what seems to be) this issue now during our deployments. Here’s the stack trace:

System.ArgumentNullException: Buffer cannot be null. Parameter name: buffer at System.IO.MemoryStream..ctor(Byte[] buffer, Boolean writable) at Couchbase.AspNet.SessionState.CouchbaseSessionStateProvider.SessionStateItem.Load(String headerPrefix, String dataPrefix, IBucket bucket, String id, Boolean metaOnly) at Couchbase.AspNet.SessionState.CouchbaseSessionStateProvider.SessionStateItem.Load(IBucket bucket, String id, Boolean metaOnly) at Couchbase.AspNet.SessionState.CouchbaseSessionStateProvider.GetSessionStoreItem(IBucket bucket, HttpContext context, Boolean acquireLock, String id, Boolean& locked, TimeSpan& lockAge, Object& lockId, SessionStateActions& actions) at Couchbase.AspNet.SessionState.CouchbaseSessionStateProvider.GetItemExclusive(HttpContext context, String id, Boolean& locked, TimeSpan& lockAge, Object& lockId, SessionStateActions& actions) at System.Web.SessionState.SessionStateModule.GetSessionStateItem() at System.Web.SessionState.SessionStateModule.BeginAcquireState(Object source, EventArgs e, AsyncCallback cb, Object extraData) at System.Web.HttpApplication.AsyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

These only occur briefly and then seem to go away…

Thanks - H

@unhuman -

It looks like the downstream effect of another error. If you have logs, please post them to the ticket it might help isolate the problem.
