WARNING

DO NOT modify any of these parameters unless you have read this property description. Incorrect settings can cause the Wrapper to fail to operate as expected.

Number of seconds for the interval between Wrapper ping requests to the JVM.

The default value is "5 seconds", with valid values in the range of "1" to "3600" seconds.

Example: 
wrapper.ping.interval=5

While debug output is enabled, the default ping log output can be overwhelming. Rather than reducing the actual ping interval, consider using the wrapper.ping.interval.logged property to reduce the number of actual pings which get logged.

WARNING

Some users have requested this due to concerns about the load imposed on the system by the Wrapper pinging the JVM. However, the Wrapper's ping mechanism is very light weight and imposes almost no load on the system. Having a short ping interval and corresponding wrapper.ping.timeout allows the Wrapper to respond quickly to a frozen JVM. It is advised that you not touch this property.
