Finally caught it off-guard and used a htop with it.

Memory is full to the brim by the 7 instances of browserd that makes everything else swap out. Each use 9.7% of the system's memory.

Restarting... No use

/usr/sbin/browserd -s 1664 -n RTComMessagingServer

and then more underneath, with lower usage.

Started Angry birds to make it swap out, they were a bit unhappy at first (angry?), but after exiting htop reported 169 M used, with browserds dropprd to some 6% or so.

Are those the instances rendering the conversations? If so, what's taking so long, it's not like it's a long job I don't have that many conversations.

Maybe it's that and the media daemon daemoning.
