It often is :-)

I'm running a fairly recent version of -current but it still happens.

Since I use Java, the memory limits are set higher and the box only has 512M.
If you have more memory, it might not feel so bad to you.

$ ulimit -a
time(cpu-seconds)    unlimited
file(blocks)         unlimited
coredump(blocks)     unlimited
data(kbytes)         3145728
stack(kbytes)        2048
lockedmem(kbytes)    169933
memory(kbytes)       509800
nofiles(descriptors) 500
processes            160
sbsize(bytes)        unlimited

The machine is unusable while it frees pages for the 'more' process.
'more' doesn't respond, not even after paging has stopped.
I normally have LESS='-e' in my environment but removing it makes no difference.

If you want more info, or for me to try something, just let me know.
