Could not create the Java Virtual Machine.

[nidhis]

Hi Team,

We are facing below error while restarting jira, its showing page can not be displayed:

Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit. Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=384m; support was removed in 8.0 Unrecognized option: - Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit.

Please suggest at the earliest

Further to the comments from Nic above. I suspect that you have recently updated the JVM from 7.X to 8.X and the options required are slightly different. Could you also provide the fill set of JVM options that are currently defined. 
From your initial message you can see that the MaxPermSize=384m is no longer a recognised options . The complete list of valid options are shown at https://docs.oracle.com/javase/8/docs/technotes/tools/windows/java.html#BABCBGHF

The maxPermSize warning can be ignored.  But you haven't given us the rest of the log that tells us what has gone wrong.  There should be more than this, either before or after the bit you've posted (sometimes both) which should tell you what the problem is.
