[kde-solaris] Failed to accept ICE connection - again...

Oh ... yes, there is. It looks like you are running into the 256 per 
process file descriptor limit on SunOS.

It is fairly easy to raise these limits on SunOS: add the following 
two lines at the bottom of /etc/system:

set rlim_fd_max=8192
set rlim_fd_cur=1024
(requires root permission to do)

and then reboot.

After reboot, you should see

prompt%> ulimit -Hn


prompt%> limit -Sn

which means the soft fd per process limit is now (1024 - 1) and hard 
limit is (8192 - 1) -- ulimit -n reports file descriptor limits -1.

This should prevent hitting this barrier in the future. I am surprised 
that you have not seen any errors in the kde log -- something similar 

setrlimit: not owner

because my Solaris patches for KDE contain explicit code to raise 
these file descriptor limits for those processes which require it, 
and dcopserver is definitely one of them.

Please let me know.
