Bro typically does consume quite a bit of memory and you're a bit tight on memory for the number of workers you're running.
A common problem is that sometimes there will be state tables that grow too large. If you load misc/profiling then you should have a prof.log in each of your processes spool directories (they don't log centrally like other logs). Every so often in there will be an indication of the largest global variables and you can look at that for a start to see if some script is just holding on to more state than you'd like it to.

At least memory upgrades are just about the cheapest and easiest upgrade you could possibly do with your system. :)
