Console runs out of memory (PermGen). An inadequate PermSize setting in the server, while hosting web applications like the administrative console can result in errors like this in the error log:

[02/Mar/2016:07:50:27.017 -0600] threadID=2 category=UTIL
    severity=SEVERE_ERROR msgID=-1 msg="The server experienced an unexpected
    error. Please report this problem and include this log file.
    OutOfMemoryError: PermGen space
    (\nBuild revision: 22496\n"

This is only relevant for servers running Java 7.
