GWIA crashes when receiving external appointment confirmation

Internal user sends an appointment request to an external contact.

After the external contact accepts/declines the appointment, when the return confirmation hits the GWIA, the GWIA will crash.

Without knowing the hardware involved, this is most likely related to TSX / elision problem.

Open /etc/ld.so.conf with an editor and add the following line at the beginning.
/lib64/noelision

When done, please save the file and run /sbin/ldconfig

Once completed, restart the GWIA and test again.
