Question

Glassfish application server stops responding on certain port after some period of time

Asked by: darkapple

I  have a glassfish application server Version = Sun GlassFish? Enterprise Server v2.1 (9.1.1) (build b60e-fcs) running in production and every day or so stops responding on the https port (8181) and other ports(8080). Once the server stops responding, other application hosted with that port number stops responding. I've hosted two application in the server.

I searched for clue in log files but could not get one.

I've set thread size to 200.

In netstat i can CLOSE_WAIT status for different hosts.

The server needs to be restarted after it stops responding.

>>In netstat i can CLOSE_WAIT status for different hosts.

Does netstat tell you it's still listening on those ports or not?

 

by: objectsPosted on 2009-05-21 at 23:56:00ID: 24448248

sounds like you have run of of connection threads.
do a thread dump to check the state of the threads

 

by: CEHJPosted on 2009-05-22 at 00:10:38ID: 24448329

Anyway, if it *is* still listening, that rules out tcp/ip problems probably and you need to see if you enough allocated resources. http://blogs.sun.com/binublog/entry/monitoring_in_glassfish is a good place to start

 

by: darkapplePosted on 2009-05-22 at 00:18:20ID: 24448361

*.8181 seems to be in LISTEN status
there are other ESTABLISHED status also.

once i'll check the state of the threads

 

by: objectsPosted on 2009-05-22 at 00:20:17ID: 24448370

yes it will still be listening, the error would be different if it wasn't listening

 

by: darkapplePosted on 2009-06-16 at 03:50:06ID: 24636678

i've migrated the glassfish to another pc and now its working fine. but now the i'm getting errors like

Caused by: java.sql.SQLException: Error in allocating a connection. Cause: In-use connections equal max-pool-size and expired max-wait-time. Cannot allocate more connections.
       at com.sun.gjc.spi.base.DataSource.getConnection(DataSource.java:115)
       at org.hibernate.ejb.connection.InjectedDataSourceConnectionProvider.getConnection(InjectedDataSourceConnectionProvider.java:47)
       at org.hibernate.jdbc.ConnectionManager.openConnection(ConnectionManager.java:423)
       ... 80 more


i tried closing all connection in my database manager class. i think the glassfish server is not returning the connections to pool.

 

by: darkapplePosted on 2009-06-21 at 00:19:32ID: 24676491

i guess the jpa i'm using with my ejb is not releasing connection to the pool.

thanx guys i've found out the hole in my application code.

i'm using enity manager factory using the datasource from glassfish. Also in one part, i'd accessed the datasource through jndi which i forgot to close. It was creating problems.
