The following has be reported by IBM LTC:  
Benchmarking(ab) failed in RHR2 testing


Hardware Environment:
 Hostname: plinuxt8.cn.ibm.com
 Model:    p630
 HMC  :    plinuxt1.cn.ibm.com
Firmware Environment:
 RM3R041029
Software Environment:
 RHEL4 Beta2 isos.
 kernel : 2.6.9-1.648_EL
 rhr2 packages: rhr2-rhel4-0.9-14.9b.noarch.rpm

Steps to Reproduce:
1. Install rhr2-rhel4-0.9-14.9b.noarch.rpm
2. setup rhr2 test env
3. do NETWORK sub-test by redhat-ready.
  
Actual Results:
 NETWORK test fail
Expected Results:
 NETWORK test pass

Additional Information:
[root@plinuxt8 14]# cat error.log 
12+0 records in
12+0 records out
apr_poll: The timeout specified has expired (70007)
[root@plinuxt8 14]# uname -r
2.6.9-1.648_EL

Jun,
 Please provide more infomation on setting the env. and how the test
was run.

Mark,
What was the resolution for bug 11829? I can not get anything out of
that bug.
Was it a testcase or kernel issue?

Thanks

NETWORK requires a remote machine to talk to.  On this remote machine
a user 
with ssh, apache bench, and mount permissions is required. The default
user 
is "root"; this may be overridden in /etc/rhr/tests.conf. and also we
should 
privode the remote machine to be contacted in /etc/rhr/tests.conf. 

Please do RHR configuration under directory /etc/rhr. 


Jun,
is this recreatable? and how often?

Yes, this is recreatable. see following function in NETWORK script.

tcp_test(){
 service httpd start
 scp $httptestfile $RHRUSER@$SERVER:~/httptest.file
 ssh -l $RHRUSER -x $SERVER 
     "ab -c 128 -k -n 256 -p ~/httptest.file $ipaddr/httptest.file"
}

ab is a tool for benchmarking Apache (HTTP) server. 
option "-n" -- Number of requests to perform for the benchmarking session.

If we decrease number of requests, we can pass this benchmark. otherwise if we 
use default(256) number, it failed exactly.

As well recreate this bug on castorlp1.upt.austin.ibm.com which is a SF2(Power5) 

Comment 4 David Lawrence 2004-11-22 17:11:39 UTC
Changing product.

Comment 5 James Laska 2004-12-15 18:34:34 UTC
In discussion with rlandry, it appears this is a known issue (dealing with
apr_pool timeout issues).  Rob, are there any workarounds to the problem?

Comment 8 Rob Landry 2004-12-21 19:56:06 UTC
still work issue; still effects 0.9-16-pre-rc1.1 package.

----- Additional Comments From bujunhui.com  2004-12-27 04:00 EDT -------
Recreate this bug with rhr2-rhel4-0.9-14.9i.noarch.rpm on rhel4-pre-rc2.

Fyi.

I'd like to move RHR bugs to Ship Issue as this will impact the RH 
certification of our power hardware.  Thanks.
