AMETHYST supervisor error: invalid transaction handle

[John Richard Procter]

It sounds like the database connection was lost.

AMETHYST server uses TCPIP.

• If the network cable was unplugged it can cause this error.
• Check your log files for errors:
  1. Check the system events log of the AMETHYST Server.
  2. Check the Firebird log.
  3. Check the AMETHYST server log.
  4. Check the AMETHYST supervisor log.
  5. Check the system events log of the AMETHYST Supervisor.
  
  
  AMETHYST uses the network card to connect to the database. When
  you get the error, ping the server (even if it is on the same PC
  as the supervisor). If the network connection is down,you will
  get this error.
  
  Under investigation!
