<<< relevant output -- one long line >>>
19847 execve("/usr/sbin/named-xfer", ["/usr/sbin/named-xfer", "-z", "nylug.org", "-f", "/var/cache/bind/db.nylug.org", "-i", "/var/cache/bind/db.nylug.org.ixf"..., "-C", "1", "-P", "13568", "-T", "nylug.org.19558", "12.33.122.126", "axfr"], [/* 19 vars */]) = -1 EACCES (Permission denied)
