webcache ports hung in CLOSE_WAIT state

Question asked by ideea on Mar 12, 2010
OS: Red Hat Linux 2.6.18-92.el5  X86_64 architecture
Alfresco version: 3.2r2

When we use the share application, ports for the webcache remain hung in a CLOSE_WAIT state. I am wondering if this may be related to the HTTP 500 errors that we are receiving:

org.alfresco.web.framework.render.PresentationUtil.handlePageRenderProblem(PresentationUtil.java:215)
org.alfresco.web.framework.render.PresentationUtil.renderPage(PresentationUtil.java:90)
org.alfresco.web.site.servlet.DispatcherServlet.dispatchPage(DispatcherServlet.java:512)
org.alfresco.web.site.servlet.DispatcherServlet.dispatch(DispatcherServlet.java:389)
org.alfresco.web.site.servlet.DispatcherServlet.service(DispatcherServlet.java:165)
javax.servlet.http.HttpServlet.service(HttpServlet.java:717)

catalina.out:

WARNING: RMI TCP Accept-50506: accept loop for ServerSocket[addr=0.0.0.0/0.0.0.0, port=0, localport=50506] thrown java.net.SocketException: Too many open files.

There is no entry for number of files (nofiles)  in limits.conf and ulimit -a shows that open files is (-n) 1024.

Thanks. Any help would be appreciated.
