Slow floating license checkout

The following issues can cause slow license checkouts and result in longer compile times:

  • 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
  • Intel® License Manager para FLEXlm*
  • licensing
  • checkout
  • Floating License
  • Long license checkout on Linux with ipv6


    There is a delay of ~25 seconds when a floating license is checked out.


    Linux* RHEL/CentOS* v7.2

    Root Cause:

    There is a bug in Red Hat 7.2 which adds a 25 second timeout to a library call used to checkout a floating license when IPv6 is disabled.  Bug is described here.

  • How to Add Users to a Floating License

    A floating license owner can share a floating serial number (SN) with other users from the same email domain. However, it cannot be a public domain such as Gmail, Yahoo, etc. By registering the SN each person will be added as a user of that license.
