I have used acid for all deletion. (nothing manual) 

Is ACID suppossed to yank the data portion of the packet when you delete?

A couple of clarifications:

- If you deleted events from the database manually, make sure to delete
the corresponding information from all tables (i.e. event, iphdr,
tcphdr/icmphdr/udphdr, data, opt).  Otherwise, the database will be left
in an inconsistent state.

- the event cache does not store any data on the packet payload

Assuming you have deleted a number of alerts from the database without
using ACID, the cache will need to be rebuilt.  Issue the following
command from the mysql command line:

mysql> DELETE FROM acid_event;

This command will delete the entire cache.  To recreate it, use the
maintenance page or simply enable auto-updating of the event cache.
