Communication Channel RFC Sender getting error suddenly

[former_member182004]

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.

Ok, I'll try it to see what happens.

Hi

These Exception will occur due to timeout. You can avoid these error by "Increase the timeout time".

Also check your RFC destination is up or not.

Hi,

This happens if the RFC connection pool is not instantiated or may be cache failed to auto-refresh....And manual restart of RFC channel resolves it.

Refer page 8 in the RFC troubleshooting guide.
