Hello, We run a production environment with over 30 Glassfish servers,
providing web services that are invoked by our client applications. We have
recently upgraded our servers to Glassfish 3, previously we were running
Glassfish 2. Since doing this we have been experiencing an intermittent issue
where the server logs the error containing: GRIZZLY0023: Interrupting idle
Thread: http-thread-pool.... It repeatedly logs this every 2ms and the server
no longer serves any requests. It is not possible to stop the domain, to
resolve the problem the JVM has to be forced to close and then the domain
started again. The issue mainly seems to happen overnight when we suspect the
servers are experiencing no load. Some nights none of the servers experience
the issue but this is rare (last night 3 servers failed). We are running JVM
1.6.0_33, Glassfish 3.1.2.2 (build 5) and the OS is Linux centos
(2.6.32-279.2.1.el6.x86_64) which is running in a virtual environment. There
have been various threads on forums about this issue and we have tried the
patches suggested but with little success. On Glassfish 2 we had to switch
off the Grizzly connector and use the Coyote one because of an epoll selector
bug but there does not seem to be this option on v3. Perhaps someone could be
so kind as to suggest the areas where we can enable logging and possibly help
determine the cause? An obvious starting place to enable logging would appear
to be com.sun.grizzly.config.GrizzlyServiceListener. Thank you.
