Average images per Home Page almost always fails
Hi Olio Experts,
I now have my system running apparently correctly, with no errors in
the apache logs except for the "deprecated" messages like:
[Wed Feb 10 18:34:53 2010] [error] [client 10.236.44.157] PHP
Deprecated: Function split() is deprecated in /usr/local/apache2/
htdocs/oliophp/classes/MemCached.php on line 26
[Wed Feb 10 18:34:53 2010] [error] [client 10.236.44.157] PHP
Deprecated: Function session_unregister() is deprecated in /usr/
local/apache2/htdocs/oliophp/public_html/calendar.php on line 38
which seems to be new since PHP 5.3.
I have a system with over 20 cores, and over 32GB memory running
CentOS x64. In every run but one I have made, the runs always fail
with something like:
Average images loaded per Home Page 2.96>= 3 FAILED
My system is only 3% busy at 125 concurrent users and no disk I/O
wait shown in vmstat. I have memcached, mysql, and the filestore all
running on the SUT. Nothing seems wrong with the setup and there are
no helpful errors shown anywhere. The faban load driver system is
only about 2% busy during the test. It really isn't any different
with 25 up to 125 users.
What is the trick, if any, to make this one statistic pass? I don't
have the flexibility to change the disk or network setup in this
configuration. I am not trying to shoot for the moon here, I just
want a reproduceable stable setup at a moderately low load.
Thanks for any advice,
Eric

Yes [?]
A JIRA was just filed on the issue - I suggest you ignore this error for
now.

In reading about a dozen posts on this topic, I found two answers, 1)
"I don't know why" and 2) try running longer. Is that it?
