[phenomenon]: after the application of the updated version, there are many restart phenomena, which will occur when operating in the background through analysis.

[cause Analysis]:

Check the log of Resin, and no OutOfMemoryError is found. In the root directory of resin, an error log file hs_err_pid20194.log is found.

This situation is usually caused by JVM crash, and in most cases it is caused by the BUG of JDK. Upgrading JDK can solve the problem.

[solution]:

Test the JDK version replacement in the test environment, if there is no problem after the test, and then update the JDK version of one of the applications in the production environment to a new version on the premise of not having a great impact on users. Make sure that the problem no longer occurs, and then update another machine.
