Why would there be no space when I have 24GB of memory?
1. Any process, including the kernel can only allocate up to 4 GB of
memory on a 32-bit system (since a 32-bit integer can only hold that
many values)
2. The kernel is further constrained so the user programs can get
enough memory
3. Kernel structures for tracking and using memory are also stored
in kernel memory. 24 GB of memory with PAE probably "eats up" a lot
of those. I think you'll need to increase kmem_size (see
http://wiki.freebsd.org/ZFSTuningGuide for an example - ignore
ZFS-specific things).
It made no difference. Still the same error.
Is anyone actually using PAE with FreeBSD 6.2? I have found
practically no information using
google.
We are using it on very heavy loaded production web server. 8GB of ram,
dual xeon with HT. FreebSD 6-STABLE. about 900 process running
constantly in about 20 jails. No problems detected :)
Planning to migrate to 7-CURRENT AMD64 within a month.
