Error in replicaiton from R/3 to CRM.

Hi Gurus,

    I am trying to replicate business object, customer_main, from R/3 to CRM. However, I am experiencing error, SYSFAIL, in outbound queue of R/3 whereas, the status in CRM, RUNNING, is showing but so far, there is 0 blocks. Please advise on this error in R/3. I don't know how to solve this error in R/3. Please refer to attached image. I am getting this error in r/3. Please advise.

Thank you,
