Your problem is the extra {}s around the filehandle. Although print lets you do that, since it uses a syntax not involving a comma, flock and seek do not. So change like: 

flock({$nick},LOCK_EX);

[download]
to 
flock($nick,LOCK_EX);

[download]

The syntax you had there created a hashref with nothing in it.

You really should be checking the return value of flock, and open.

(was updated because I really should've checked what { 'whatever' } produced.)
