System is CentOS 6.8 x64.

Trying to upgrade from 2.26 to 2.31. We purchased the maintenance upgrade, and ran fop2_server --upgrade from /usr/local/fop2 while running 2.26, which seemed to work fine.

[root@asterisk fop2]# /usr/local/fop2/fop2_server --test
Flash Operator Panel 2 - Valid License (1)
Connection to manager OK!

Downloaded proper tarball into /usr/src, unzipped, cd'd into fop2, ran make install, and we get this error:

[root@asterisk fop2]# make install
/bin/sh: line 265: 23610 Segmentation fault      server/fop2_server --reactivate $NIC

Upgrade Aborted. License reactivation failed.

Be sure you have internet access from this server,
and that your code is not older than a year.

If your license has expired, you must renew it in order to upgrade,
or you can still use your current FOP2 version for as long as you want.

If you already bought an upgrade code please run the following command:

server/fop2_server --upgrade

If the upgrade is successful run make again to retry the installation.
