kmem_malloc(4096): kmem_map too small: 536870912 total allocated

[Vladimir Sharun]

I found the sources of the leak: if exim accessess ANY configuration/text 
files over NFS, there will be leak. And, how often exim will be called, then
quicker your system dies.

My main problem now is to build near-realtime mirroring solution nfs-to-local
for around 20 files (up to 1Mb everything). Any /ports solution ?

The next question to Philip Hazel: any comments why this happens ?
