    49 DESY put the `ulimit` value somewhere; perhaps in `/etc/default/security`. 
     49DESY put the `ulimit` value somewhere; perhaps in `/etc/default/security`.  They have a ulimit of 32k open file descriptors on the Solaris pools.

    5151There's no explicit setting in dCache for setting the ulimit prior to starting dCache. 
     
    5353However, there are two useful settings in `dCacheSetup` (or `dcache.conf` post 1.9.6) that may be helpful.  The 'dcache.local.shell' option names a file to be sourced.  The 'dcache.local.run.sh' option names a file that will be executed.  These files should be inside the /opt/d-cache/bin directory.

     55The most dangerous is FTP with multiple streams.  For 10 streams, you need 11 or 12 (depending on whether the door relays the data). But, there is also other sockets that are always needed (e.g., cells communication, database connections, etc).
