Getting java.io.IOException: Too many open files+ClassNotFoundException

I think this these two exceptions are occuring in differrent environment

java.io.IOException is occuring under heavy load to web server its stack trace is as follows:

JSPG0225E: An error occurred at line: 2 in the statically included file: /SessionCheck.jsp

JSPG0093E: Generated servlet error from file: /Admin/AdminInsuranceCertificates.jsp

E:\WebSphere_6\AppServer\profiles\AUSECert\temp\centraNode04\server1\AUSECert\Vero.war\Admin\_AdminInsuranceCertificates.java:259: cannot access com.bplus.natmar.LoginDetails

bad class file: E:\WebSphere_6\AppServer\java\jre\lib\core.jar(java/io/Writer.class)

unable to access file: E:\WebSphere_6\AppServer\profiles\AUSECert\installedApps\centraNode04Cell\AUSECert.ear\Vero.war\WEB-INF\classes\com\bplus\natmar\LoginDetails.class (Too many open files)

Please remove or make sure it appears in the correct subdirectory of the classpath.

]: com.ibm.ws.jsp.JspCoreException: JSPG0049E: /Admin/AdminInsuranceCertificates.jsp failed to compile :

this error always occurs in reference to logindetails class this clas is used to make a session check on different roles in our project for e.g., user having end user role should not be able to log in as a user having admin role

we have included a sessioncheck.jsp in our every jsp page in this jsp we have simply used logindetails class as useBean and called its getresource() method

above stacktrace is from our live application server

while testing same project on our local system we are not getting too many open files exception but we are getting following ClassNotFoundException

this error is occuring on concurrent clicks suppose three users click on same button then it is possible that one user gets correct output while other users experience this exception

Also one more point we are not using web.xml for calling servlets we are directly calling it giving its full path.

Thanks
