Our users of the confluence are complaining on constantly appearing exception on attempt to save data.

-----------------------
java.lang.IllegalStateException: Post too large
at org.apache.catalina.connector.Request.parseParameters(Request.java:2368)
------------------------

By reading relevant documentation and issues in JIRA I came up to the solution that this is because of default setting of Tomcat Application server for postMaxSize (default size = 2.0MB). We are currently using 5.5 Tomcat version on production.
As a workaround, by increasing the postMaxSize using server.xml from 2MB to 3MB we can make the exception to appear less frequently

Is there any permanent solution for this?
