RFC sometimes fail

Hi Experts,

I am facing a very strange situation.

We have set it up multiple Sync RFC from SAP ECC to SAP PI, one and only one of them returns a SYSFAIL but not always, looks like does one good execution and the next one is SYSFAIL and nothing reach the SENDER RFC CC.

I test with another sync Sender RFC 10 times 10 times OK.

With this one the average is 50% of the executions, and only happens with this RFC.

I did a trace of a wrong execution with the XPI_Inspector and (I reenter the user and pass in the JCo RFC provider and nothing):

"Failed repeatedly to create a repository for RFCEngine Bundle LCRSAPRFC"

"java.rmi.RemoteException: Failed to create the JCo client pool LCRSAPRFC200|EN|AS=[trigo|00|] for JCo RFC Provider bundle LCRSAPRFC; nested exception is:

Hi,

please do have a look at the OSS e.g.

2276599 - RFC_ERROR_LOGON_FAILURE: Incomplete logon data

Best regards,

Pablo

Thanks for your reply, the error is/was that they basis team cloned the PI in the same system to have 2 envioments (bad practice) and the rfc was pointing to the first available system....

Thanks
