I'm monitoring mbufs since I rebooted my server. Right now (after 2.5 hours
or so of operation) the number of total clusters has already increased to
15k. Is this a normal behaviour for a relatively idle server or will it
inevitably go through the roof in some more hours?

Well it could be coincidence, but mine are around 15k as well:

15308/2678/17986/51200 mbuf clusters in use (current/cache/total/max)

System is up since last night, and has taken a few Gb in rsync-backup and
several compile jobs.
Hasn't given me trouble (yet).
