This error message occurs when memory reserved for permanent generation of garbage collectors (GC) runs out. Other GC generations are: young generation -> tenured generation -> permanent generation.<\/p>\n

You can set the permanent generation memory pool:<\/p>\n

\r\n-XX:PermSize=64m\r\n-XX:MaxPermSize=256m\r\n<\/pre>\n
In contrast to setting heap memories:<\/p>\n
\r\n-Xms768m \r\n-Xmx1024m\r\n<\/pre>\n
For java service wrapper, add to wrapper.conf<\/p>\n
\r\nwrapper.java.additional.2=-XX:PermSize=64\r\nwrapper.java.additional.3=-XX:MaxPermSize=256\r\n<\/pre>\n
