Last updated on JUNE 29, 2015

Applies to:

PeopleSoft Enterprise PT PeopleTools - Version 8.50 to 8.51 [Release 8.4]
Information in this document applies to any platform.

Symptoms

The Web Server becomes unavailable regularly after time and heavy usage. Weblogic threads get locked over a period of time as a result of very heavy pagelet usage, and DTD validation from the html associated with these pagelets. Occasionally dump files are found on the Weblogic server.

In addition, a wget command from unix to the http site listed for dtd validation within the html pagelet results in a 503 Service Unavailable return code.

(  For example wget http://www.w3.org/TR/html4/strict.dtd )
