Hello,
I had the time to test a snapshot.
I download the bsd.mp i386 11 nov 2008 23h25
I install only the bsd.mp because I want keep the box in 4.4 stable if
something goes wrong. If that is not engouh I will have the next week a
better environnement to test it (with serial console, apc, etc).
I have a heavy apache with mod_perl that was crashing the box due to (I
suppose) heavy memory fragmentation under 4.3. I upgrade to 4.4, and that
was only a little better.
With the 44.20081111-2325 snapshot, it is really better.
What looks strange to me is that I limit the heavy perl to 10
MaxRequestPerChild in httpd.conf as a test. And when the child exist,
sometimes the swap used grows even if the memory is not exhausted.
When there are many heavy httpd process running, if I do "apachectl stop"
the machine often starts to swap to death.
But if I do "pkill -9 httpd", no problem.
The second thing, I use watchdogd but it never reboots the server.
I see some message in /var/log/messages
Nov 14 01:00:07 root /bsd: uvm_mapent_alloc: out of static map entries Nov
14 01:01:58 root /bsd: uvm_mapent_alloc: out of static map entries Nov 14
01:03:44 root last message repeated 9 times
Nov 14 01:08:25 root last message repeated 4 times
When I test the box with
http_load - parallel 200 -seconds 60 url.txt
the server sometimes freezes.
Here the last output of some tools at freeze times:
