persistentRestart
This configuration variable controls how the server handles an automatic restart. An automatic restart is initiated when maxHeapSize is exceeded (UNIX only) and when Tango detects a problem with servicing requests.
When set to true, the server first attempts to completely shut down the running server before restarting a new one. All variables in use at the time of the shutdown are preserved.
When set to false, a new server is started immediately, even before the old one is stopped. This setting ensures high server availability, but variables from the old server instance are not available in the new one. The default value is true.
