We are randomly getting "ERROR_LOCAL_ARCHIVE" error in few SFTP Sender channels. We are using Advantco SFTP adapter in these channels. Also, this is not a persistent error i.e. channels start working fine after next poling interval without any manual intervention. No message gets generated when channel throws this error. There are Advantco SFTP Sender channels related to other Business Component, which work fine without any error. We are using "SAP_XI_IDOC/IDOCFlatToXmlConvertor" bean in Module tab of affected channels. There are no additional logs available in channel monitor for this. We are on SAP NW 7.4 SP 17.
Has anyone faced this issue. Any thoughts?
