We are running SAS9.4M4 on Windows 2008 R2. I often see a process iproxy running. The executable is located in $SASHOME\core\sasext\iproxy.exe. Takes a lot of memory and has high cpu time.(In cetain case 70%+ for example with proc npar1way wilcoxon) The jobs are run through SAS Enterprise guide. What is it and what purpose it serve? Can we not disable it.
