T30-2017 Notification regarding BIOVIA Discovery Studio 2017 R2 Hot Fix 1

DS Server

Operating System
Linux

There are two separate issues in Discovery Studio 2017 R2 which are being addressed by this Hot Fix:

  1.  ​CHARMm jobs are failing with a segmentation fault error
  2. Protocols fail on updated RedHat servers. The problem may appear following an operating system update to nss and nspr system libraries or on newly installed RedHat operating systems which already include this update.

The issue occurs when the nss library version is version 3.22 or later and/or the nspr version is 4.12 or later. You may use the following commands to check the versions of these libraries:

>   rpm –qa nss

>   rpm –qa nspr

The symptom is that DS protocols will fail with an error similar to the one listed below.

 

    
Resolution:

These issues have been logged as defects DSC-27328 and DSC-27391 and are fixed in BIOVIA Discovery Studio 2017 R2 Hot Fix 1 released in June 2017.  
If you have any questions or concerns please contact BIOVIA Support.
