Hmmm. This looks a lot like the problem I have on my news server. It will run ok for a while and then suddenly start to use up all of the swap. According to top and ps no process is using that memory, but if I kill innd quick enough all will be ok. So now I have a script that runs every minute and kill and restart innd as soon as the swap usage go over some value. Not nice, but it works until someone find this thingy.
