The bug, you mentioned was how to obey Solaris limit of max 256 opened
files. In my case, the problem is not that there are too many open
files, but the fact that the number of opened files is growing
constantly.
On this forum, there were threads about similar problem, but it was
about WebServices/other HTTP connections. My client applications does
not use WebServices but IIOP and HTTP is used only to download
application using WebStart. It looks like the longer/the more clients
are using Glassfish the more files are being opened and never closed.
I managed how to increase the OpenFileDescriptorCount limit. Now it is
4096. I will see if this limit is going to be overrun eventually. The
1024 was reached always before 20-30 hours of using (depending on how
many clients were using it and for how long). I am worry that the new
limit will not solve the problem, but only increase the period before
failures :/
