When executing any operation (GET/PUT/DELETE) for the traversal and resources services I get the following error intermittently.

{
"requestError": {
"serviceException":

{ "messageId": "SVC6134", "text": "Could not persist transaction to storage back end. Exhausted retry amount (msg=%1) (ec=%2)", "variables": [ "Could not persist transaction to storage back end. Exhausted retry amount:org.janusgraph.core.JanusGraphException: Could not execute operation due to backend exception", "ERR.5.4.6134", " ] }

}
}
