PANIC happened on master

What is this alert?

When a message with severity level PANIC is written to the Greenplum Database log on the master host, Command Center raises an alert.

A PANIC message reports a critical error that requires immediate attention. A panic occurs when the system encounters an unexpected state or an error condition that could not be handled in the software. All currently executing jobs in the cluster are cancelled when a PANIC occurs.

Some examples of conditions that could cause a PANIC are:

  • Unable to access critical files
  • Full disk or memory buffer
  • Unexpected data values, such as badly formatted transaction IDs
  • Seg faults or null pointer references

What to do

Contact Pivotal Support for help before you attempt to troubleshoot the problem. Continuing after a PANIC could lead to data loss and may make it more difficult to diagnose the problem and recover your system.
