If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit).

Comment 3 Eko 2017-10-26 06:01:42 UTC

Hi Chris,

About the polls job status, we can't see any "poll job status" messages from the rhsm.log by virt-who logged. Because we don't have the permission to check the candlepin.log in stage candlepin, we only can check the "GET" Request from candlepin.log in satellite6.3, 

According to my testing, I can't find the valid "poll job state" message as you said: with an exponential backoff from 2 second polling time to 32 seconds.
How do I reproduce this issue and how to check it? could you give me some suggestions to verify this issue?  
 
The below is the log message from satellite candlepin.log about "Request: verb=GET, uri=/candlepin/status"

1). before fixed (virt-who-0.19-6.el7_4)
restart virt-who and check /var/log/candlepin/candlepin.log in satellite:
# grep "uri=/candlepin/status" before_fixed.log

when restart virt-who, there are 5 "Get" Requests for "uri=/candlepin/status", and all the request time: "2017-10-26 13:27:19"

2). after fixed (virt-who-0.19-7.el7_4)
restart virt-who and check /var/log/candlepin/candlepin.log in satellite:
# grep "uri=/candlepin/status" after_fixed.log

when restart virt-who, also there are 5 "Get" Requests for "uri=/candlepin/status", and 4 requests time is:2017-10-26 13:47:46, the last request time is: "2017-10-26 13:48:01"
