Unable to connect to remote server error while calling userprofile webservice RRS feed

  • Question

  • Our environment has two MOSS2007 farm, both are on same domain, uses NTLM authentication. Farm-1 has (intranet) based publishing portal, and it consumes user profile store from Farm-2. Both farms are updated upto Feb'11 CU.

    During "stress" test, (when user load excedds 800+ user load..we are using LOadrunner)  Farm-1 application eventlog shows "unable to connect to remote server" error..when we call http://farm2/_vti_bin/userprofileservice.asmx.

    Checked eventlog, ULS log, IIS log, SQL log. Nothing useful.

    Any idea? What else could be wrong?


    Thanks for any assitance.
