The following issues can cause slow license checkouts:
- Old license server information or license files. Check the following places for invalid licenses and delete any found:
- INTEL_LICENSE_FILE environment variable - make sure port@host is correct and any folders specified do not contain invalid license files.
- For Linux: /opt/intel/licenses
- For Windows: [Program Files]\Common Files\Intel\Licenses
- A bug introduced with RHEL\CentOS 7.2. This adds a 25 second delay to the floating license checkout when IPv6 is disabled. More information here.
- Running 2016 or newer versions of the compiler on a remote workstation. A license caching feature available in the 2015 product version was disabled in the 2016 version. More information here.
