JBoss 3.2.6 Problem

[alehandros1]

Hello,

I am running my application on JBoss 3.2.6 with embeded Tomcat, the OS is Linux. Up to now the EJBs had been accessed only from Tomcat and it's been working stable for months. Now since I created Java desktop client, every few days I get the exception bellow. There are about 60 users using the web interface and 20 the desktop client simultaneously.

Caused by: javax.naming.ServiceUnavailableException: Failed to connect to server localhost:1099 [Root exception is java.net.SocketException: Too many open files]
 at org.jnp.interfaces.NamingContext.getServer(NamingContext.java:187)
