I'm hoping someone can point me in a direction. I'm having an issue with Apache and Glassfish where a few times a week, httpd processes spawn and exceed the MaxClient setting of 256. Glassfish becomes unresponsive. They stop serving the web page.
To fix, I stop the glassfish process using kill –9 because /etc/init.d/glassfish…. stop does not complete I also have to restart httpd.
The server.log file in Glassfish throws this commonly every time…
[#|2011-08-24T08:30:09.291-0600|WARNING|glassfish3.1|org.apache.jk.common.ChannelSocket|_ThreadID=87;_ThreadName=Thread-1;|Exception executing accept

And the apache logs shows that the MaxClient Settings have been exceeded.
I currently have MaxClients set to 256.
I'm fairly new to Glassfish and I'm trying to figure out the methods to troubleshoot this.
Has anyone else seen this behavior and how have you troubleshot or fixed it?
thanks for any help.
