JCo RFC stop/hang


I have a JCo RFC setup in my J2EE Administrator. Lately i found out the service will hang/stop by itself as my program unable to call it and when i test connection in SM59 (TCP/IP) it will say timeout. Once i restart the service then only it can work. I check the dev_jrfc.trc file and i noticed this error message.

RfcGetException rc (7) message: One of the field names in the SELECT clause was not recognized.

Would like to know am i checking the correct trace file. Also is this error message related to my program or Netweaver server?
