Communication Channel RFC Sender getting error suddenly

40 Views

Hello gurus,

I'd like to ask you about a problem, we have many interfaces from RFC to SOAP synchronous, the CC RFC sender, in an average of once per day, gets into red colour with this error:

Sender channel 'CC_RFC_SENDER_L0_MAESTROS' for party '', service 'BS_LD0_100'
Error can not instantiate RfcPool caused by:
com.sap.aii.adapter.rfc.RfcAdapterException: error

I don't know the reason of this.. but simply just stopping and starting the CC it gets into green colour again..

Does anyone know how to solve this?

Regards,

Juan.
