Now I'll try -hackers... I've just configured my first server with 4G RAM. To use it, I had to select PAE in kernel config. I was a little bit troubled by it's advice not to use modules (is it that critical?), but got it running. But when it is running on PAE, NFS statd refuses to run: # /etc/rc.d/nfslocking start Starting statd. rpc.statd: unable to mmap() status file: Cannot allocate memory Segmentation fault # Using strace I found it was trying to mmap the status file, at /var/db/statd.status: open("/var/db/statd.status", O_RDWR) = 10 mmap(0, 268435456, PROT_READ|PROT_WRITE, MAP_SHARED, 10, 0) = -1 ENOMEM (Cannot allocate memory) It's really strange to have mmap len = 256M, specially because the file is always small. But it works without PAE, and do not work with PAE. And it is described in the handbook: http://www.freebsd.org/doc/en_US.ISO8859-1/books/faq/book.html#STATD-MEM-LEAK Also, I tought PAE was only needed when we had MORE than 4G. But without PAE the system shows only 3.5G: - Without PAE: Jul 25 16:34:41 zeus kernel: real memory = 3757965312 (3583 MB) Jul 25 16:34:41 zeus kernel: avail memory = 3678429184 (3508 MB) - With PAE: Jul 25 17:09:01 zeus kernel: real memory = 4831838208 (4608 MB) Jul 25 17:09:01 zeus kernel: avail memory = 4193112064 (3998 MB) If I could use the whole 4G, or at least lose less than 512M, I'd prefer to stay off PAE. Any help you could give me? TIA, Jonny PS: sources fully updated to 6-RELENG from last week. -- João Carlos Mendes Luís - Networking Engineer - jonny@jonny.eng.br
