Error: java.lang.OutOfMemoryError: Java heap space

Error Message

When logging in to the ArcGIS Java Manager URL using the Internet Explorer web browser, the following error occurs:

"java.lang.OutOfMemoryError: Java heap space".


This error occurs when the ArcGIS Server Object Manager resides on a host computer that has underscore characters in its name. This is because underscore characters in Domain Name System (DNS) host names are illegal in Internet Explorer.

Solution or Workaround

This error is resolved by removing any underscore characters in the host name. Work around this issue by using either the IP address in Internet Explorer or by using the Firefox Web browser instead.
