Solution to the Too many open files problem.
I have further input on the too many open files issue. On SOLARIS the
soft and hard limit for number of open files is 256 for a non root user.
For a root user the soft limit is 256 and the hard limit is 65536.
So if you start the GF Appserver as root you will have a hard limit of
65536. You will not get too many open files.
If on the other hand you start the GF Appserver as a non root user you
will have a hard limit of 256. This will most likely cause too many open
files from appserver.
WORKAROUNDS
-----------
1) Run the GF Appserver as root. You will get the 65536 (64K) hard limit
2) If you run the GF Appserver as a yourself do the following. From your
terminal window do an "rlogin back into your system". This will give
you a "in.rlogind" process that is owned by root. You can then start
the GF Appserver as yourself. This will give you a hard limit of 64K
because the "in.rlogind" process is owned by root. I have tried this
and it works. So to summarize:
% rlogin host -l yourself
% asadmin start-domain //Your GF Appserver will now have 64K
//open file limit

I always close the producer, the session and the connection (when sending). Handling the message is currently doing nothing (or almost nothing, depending on configuration), but always succeeds.
