That's what I do at the moment. That's what I'm trying to avoid.

At the moment, snort logs to binary files, I use the -b option. To get the packet contents I ssh to the snort box, send snort a HUP so it closes the file & opens a new one. I then scp this to my machine, run snort on my machine against the binary file to extract the packet contents and then I examine the packet.
This takes ~ 15 minutes to do, for every false alarm. If it is towards the end of the day, the binary file can be > 400MB. If I could see the packet contents in the alert, It would take me about 10 seconds to look at the packet and see if it's a false alarm or not.

That's what I'm asking, is there any way to get snort to log packet contents in the alert?

Why not build tcpdump on your non-snort box and use 'tcpdump -X -r snort.log.file' to extract the contents. I don't see why you need to restart snort to get the data dumped since you're logging application data to tcpdump format file anyway. Am I missing something? If you just want to checkpoint the snort logs you can send it
a HUP signal. If you started snort with a -b flag, and using the default log file name snort will create a new binary log file with a different timestamp.
