@Dinesh Reddy G It is possible that first look up for this class might have failed for some DB reason which may not be logged and cuasing issues.

To avoid it and load the class during startup itself, apply below settings in PRConfig, restart servers and test behavior.

<env name="initialization/preloadengineclasses" value="true" /> <env name="initialization/preloadenginejars" value="datastore.jar" />  

if it still doesn't help, please create an INC and involve GCS for further troubleshooting.
