If yes, what's the correct way to change that maximum? Do I get errors in the logs when the maximum is reached?

It just gives no output and the terminal does not respond anymore. No errors in the logs. I've seen it in the firefox profile, like this: /home/paul/.mozilla/firefox/0k48lsbe.default/ The browser hangs then. No problems in other directories of the same user. I am using homedirs on NFS4 with LDAP and MIT Kerberos on Debian Wheezy with a 3.16 kernel. sec=krb5i. With regards, Paul .
