The "Link died" message in Gaussian03 indicates that the connection between the client and server has been lost, causing the calculation to terminate prematurely.
To fix the "Link died" issue, you can try restarting the calculation from the beginning, making sure that the connection between client and server is stable.
Yes, the "Link died" message can affect the accuracy of your Gaussian03 calculation as it interrupts the normal calculation process and may cause data loss.
Some common causes for the "Link died" message in Gaussian03 include unstable network connections, server or client crashes, and memory or disk space issues.
While it is not possible to completely prevent the "Link died" message in Gaussian03, you can minimize the chances of it occurring by ensuring stable network connections, regularly monitoring disk and memory usage, and using stable and updated versions of Gaussian03.
