2. Re: Too many open files exception JBOSS 4.2
ajayks Feb 26, 2008 1:06 AM (in response to ajayks)Hello JaiKiran,
Thanks for the reply.
I am using JDK1.5 of SunMicrosystem and the version of JBOSS I have used is 4.2.2.GA.
The following are the stack trace for the exception I have got:-
11:10:22,744 WARN [UILServerILService] Failed to setup client connection

11:10:22,751 INFO [STDOUT] exception:Cannot authenticate user; - nested throwable: (java.io.EOFException)
I have found after getting above error the AS statas throwing same error whenever client tries to call EJB deployed in JBOSS.
I think there is some configuration issue either at OS level or JBOOS level
like how many file/ports can be opened by the J2EE application.
Thanks to give me solution of my problem.
with regards,

4. Re: Too many open files exception JBOSS 4.2
eightmd Mar 11, 2008 1:14 PM (in response to ajayks)Was there any resolution to this? We are seeing the same problem. We are front ending JBoss with Apache 2.2.6 and using JBoss 4.2.2GA. We are on Linux FC6. After some time it runs into the Too many open files problem. This is under a heavy test load, but we still expect it to recover and we didn't see this issue with Apache 2.2.0 and JBoss 4.0.3.
I've seen various issues listing this same error but I haven't seen any solutions. Our max file handles per user is 1024 which would see sufficient and the total max is very large.
We see many open sockets on the 8009 port which is the port that JBoss users to listen to the Apache AJP connector. I believe they connections get into a CLOSE_WAIT state and seem to stay there.
Anyone figure a way out of this. Just bumping up the number of max connections will just put the problem off till later. -

georges.goebel Mar 14, 2008 11:18 AM (in response to ajayks)Hi,
I had the same problem with the "close_wait" connections. I managed to solve the problem with the workaround of using the jbossnative 2.0.3 library

asazhin Jan 15, 2009 10:24 AM (in response to ajayks)Georges,
Could you explain me how you solved "CLOSE_WAIT" problem by jbossnative?
We're using Apache(front-end)+JBoss(RedHat) too and we have "CLOSE_WAIT" problem on AJP connector too. As result "CLOSE_WAIT" problem causes "too many open files".
