"Error occurred during initialization of VM" while re-starting jira

Vinutha Vasan asked this question · 261 karma ·

HI All,

I am facing below error while shuting down jira instance,

"Error occurred during initialization of VM. Could not reserve enough space for object heap."

Any Idea?

JAVA_HOME is also set properly.

I suspect the issue here is that you have assigned more memory for the JVM to use than is actually available on the server. Check the JVM_MINIMUM_MEMORY and JVM_MAXIMUM_MEMORY values as defined in the|bat file to ensure they are within an available amount of memory, also ensure JIRA_MAX_PERM_SIZE is set to about 256mb.

After you've checked these, make sure you havn't defined any that may overwrite these within a JAVA_OPTS environment variable.

As a rule, JVM_MAXIMUM_MEMORY should be set to three quarters your available memory but should not be higher than 1.5/2Gb.
