REST API access token becomes invalid before its expiration time.

[Anonymous]

Hi,

Working with REST for Marketo, sometimes the access token becomes invalid before its expiration time (got response with error code 601 - Access token invalid:http://developers.marketo.com/documentation/rest/error-codes/  )

Does anyone also encounter this? What we might have done wrong?
