I've still got severe memory leaks with NetBSD on a SMP SS10 with 320MB of 
RAM. The machine is only running as a mail server with Postfix as the MTA. 
The current kernel is 2.0_RC4, and in my opinion the problem got much 
worse than with previous releases. I still have to reboot the machine once 
a day otherwise it will stop with errors such as "out of buffer space" and 
the like. vmstat -m  reports about 10MB allocated and will grow up to 
nearly 70MB without ever decreasing. This kernel is definitely *NOT* a 
release candidate!
For more details please look at my previous postings to this group.
