Hi. Odd occurrence here which we have created a work-around for we thought we should share but were wondering if anyone else has experienced and overcome. Pete Symptom: NMAP2 not plotting sfc obs (no errors in the error box). SFMAP plots obs just fine. SFLIST list obs just fine. NWX will list obs just fine. Attempted Corrections (which did not work): Recompiled successfully. Removed old version from system, ensured no other nmap2 executable existed on the system, rebooted, pointed system to newly recompiled version. Made sure Gemenviron was correct for our system. Symptoms persist. Workaround: cd to the location of the Gemenviron file, resource, then launch nmap2. We have thus renamed the nmap2 exe to nmap2.orig and created a c-shell script in the $GEMEXE dir called nmap2 to perform these steps (cd $GEMPAK/.. source Gemenviron os/linux64/bin/nmap2.orig "$1" "$2") Notable: We feel this has something to do with RHEL errata updates we accept and invoke since this began yesterday after we invoked an update. We thought a recompile would rectify the problem but it did not as the recompiled version exhibited the same symptoms. The workaround also was effective for the recomplied version. ----------------------------------------- The information contained in this message is intended only for the personal and confidential use of the recipient(s) named above.
