Memory leak using jsp tags on an app deployed on glassfish
----------------------------------------------------------
Key: WW-3751
URL: https://issues.apache.org/jira/browse/WW-3751
Project: Struts 2
Issue Type: Bug
Components: Other
Affects Versions: 2.3.1.1, 2.3.1, 2.2.3, 2.2.1.1, 2.2.1
Environment: Windows 7 Professional (Microsoft Windows version 6.1
Build 7601:Service Pack 1) 64 bit
Processor: Intel Core i5 CPU 650 @ 3.20GHz 3.33 Ghz
Ram: 6.00 GB
GlassFish Server Open Source Edition 3.1.1 (build 12).
It also happens in production environment with different hardware configuration
running Linux
Reporter: Marco Malavolta
I have some webapps based on Struts 2 framework.
I use JSP tags, even sometimes with nested Struts 2 tag (FreeMarker).
Every time you call with a single jsp jsp tags JspWriterImp a new instance is
created with more or less the contents of the tag (instead of reusing the same
object stored in memory.
This causes a loss of memory, because these objects are located in the old
generation heap 'til the web application is restarted
After a few days / weeks depending on the traffic that you need to restart
because of irresponsiveness.
I also created a Jira issue on GlassFish
(http://java.net/jira/browse/GLASSFISH-18316), where I posted a screenshot and
a sample application to reproduce the problem.
Basically I'm not sure if it's a struts problem or a problem of glass fish.
Perhaps the second hypothesis is more likely
Feel free to close it if you feel that the problem is solely related to
Glassfish
