Struts form tag increases the file descriptors to struts2-core-2.0.11.jar there
by causing "Too many files open" exception
--------------------------------------------------------------------------------------------------------------------------
Key: WW-2474
URL: https://issues.apache.org/struts/browse/WW-2474
Project: Struts 2
Issue Type: Bug
Components: Plugin - Tags
Affects Versions: 2.0.11
Environment: Apache 2.2, Tomcat 5.0.28, Java 1.5, Struts 2.0.11
Reporter: Santhosh
Whenever I try to access a file with struts2 form tag, the server opens a
certain number of file descriptors to struts2-core-2.0.11.jar and nevers
releases them.
Here is the content of the sample file:
<%@ taglib uri="/struts-tags" prefix="s" %>
<%@ taglib uri="http://tiles.apache.org/tags-tiles"; prefix="tiles" %>
<s:form action="Search" onsubmit="return checkSearch(this)">
<p class="btn"><input type="image" src="i/btn_search.gif" /></p>
</s:form>
Number of file descriptors after server restart:
lsof | grep struts2-core-2.0.11.jar | wc -l
1
Number of file descriptors after accessing the file:
lsof | grep struts2-core-2.0.11.jar | wc -l
9
On rfereshing the page, the number of file descriptors keeps on increasing.
AFAIK, the server is not creating file descriptors for any other struts tag.
This is the content of another file:
<%@ taglib uri="/struts-tags" prefix="s" %>
<%@ taglib uri="http://tiles.apache.org/tags-tiles"; prefix="tiles" %>
<s:set name="personName" value="santhosh"/>
Hello, <s:property value="#personName"/>. How are you?>
The file descriptor on executing this file did not increase.
