Problem:

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

Environment:

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.

Workaround:

  • Enable IPv6 on the system (if possible)
  • Remove the hostname from /etc/nsswitch.conf as described in bugzilla, for example:
    /etc/nsswitch.conf:
    From:
    hosts:      files dns myhostname
    To:
    hosts:      files dns
