Description Liushihui 2014-06-05 09:50:32 UTC 
Description of problem:
After system has been registered to SAM server, Though virt-who run normally, it will pop up some error message during communicate with subscription manager occasionally.

Version-Release number of selected component (if applicable):
virt-who-0.9-4.el5
subscription-manager-1.11.3-5.el5
python-rhsm-1.11.3-3.el5

How reproducible:
Always

Steps to Reproduce:
1. Register system to SAM server and make sure virt-who run at libvirtd mode normally
virt-who configuration:
VIRTWHO_BACKGROUND=1
VIRTWHO_DEBUG=1
VIRTWHO_INTERVAL=5
2. Check the virt-who status
[root@dhcp-128-110 libvirt-test-API]# service virt-who status
virt-who (pid  32168) is running...
3. Check the virt-who's log in the /var/log/rhsm/rhsm.log

Actual results:
virt-who run normally, But sometimes it will generate some error log when communicate with subscription-manager
in the log file. For example: "SSLTimeoutError: timed out" and "RestlibException: Runtime Error Batch update returned unexpected 
row count from update [0]; actual row count: 0; expected: 1 at org.hibernate.jdbc.Expectations$BasicExpectation.checkBatched:81
". Please see the detail in attachment.

Expected results:
virt-who should communicate with subscription-manager normally when it's running .it shouldn't pop up any error messages in the log file.

Comment 2 Radek Novacek 2014-06-06 11:24:15 UTC 
SSL timeout error doesn't come from virt-who, it's either python-rhsm or SAM. The second one is more probable (because of the exception org.hibernate.jdbc.Expectations$BasicExpectation.checkBatched).

Will reassign it to python-rhsm for now, it might need some check for this error.
Comment 3 Liushihui 2014-07-15 08:34:37 UTC 
In the stage candlepin, virt-who will occur similar error messages when it run at the vdsm mode and rhevm mode.
1. If virt-who run at the vdsm mode, virt-who sometimes will pop up the following error messages :

2. If virt-who run at the rhevm mode, virt-who sometimes will pop up the following error messages :

Comment 12 William Poteat 2015-05-12 19:20:37 UTC 
Please open a bug with virt-who component to limit the interval at no less than 1 minute. A virt interval of 5 seconds is not realistic.
Comment 13 Liushihui 2015-05-13 01:53:01 UTC 
I have opened a bug 1220977 to track this problem.
Comment 14 Chris Snyder 2015-09-02 20:49:57 UTC 
The problems here will be addressed in the virt-who component under bug 1220977
