This is a "normal" error message on Linux (at least, maybe other OS's as 
well).  Cyrus tries to set the fdlimit to -1 (max).  It will fall back to 
setting the fdlimit to your system's max, which usually depends on the 
value set by ulimit.  In my cyrus init script, I put:

# Crank up the file limits
ulimit -n 209708
ulimit -u 2048


to increase the fdlimit and process limits before starting cyrus.
