Snort load error with rule sid 21349

The latest server-other.rules file contains this rule:
alert tcp $EXTERNAL_NET any -> $HOME_NET [1024,5555] (msg:"SERVER-OTHER
HP OpenView Storage Data Protector stack overflow attempt";
flow:to_server,established; content:"|FF FE 32 00 36 00 37 00 00 00|";

I include this in my snort.conf. Then when I do "service snortd start"
it fails and this error is in /var/log/messages:
snort[8808]: FATAL ERROR: /opt/catbird/lib/snort/server-other.rules(382)
