4.52 seems to be ok here, with one exception:

rpc.lockd has a HUGE memory leak.  The result is that it will eventually
consume all the physical memory in the machine (and it appears to plock()
it's memory so it can't be paged out!)  This has a most undesirable outcome,
of course :-)

I have reported this to MIPS; they're working on it.

No other problems I have noticed...

Check rpc.lockd and see what it's current memory usage is (this is assuming
you're exporting one or more filesystems, or mounting some remotely from
elsewhere).
