we have recently deployed a jboss based application to a production server -
after 7 days of perfect performance - the sys admin tried to logon
using jass- role based auth (user/role properties file)
and failed every time.
after watching the logs i have noticed an I/O Exception- too many open files -
now thats odd -
and after further tests i noticed that the thread count is always rising .
after 3 days the thread count is 400 !!
so first how can i isolate the leak to find if its in the WEB/EJB container ?
considering the fact that i cant physically access the server only through a secured shell - how can i find the source of all the threads?
we are using Jboss 4.0 on Linux fedora 2 with jdk 5(tiger)
if anyone has any advise or idea ...
