RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). 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). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:

vmstat 5 fails intermittently with "floating point exception"

Floating point exception

Sometimes, it will run for some time before failure, but seems most likely to fail when the machine is idle. I have never seen a failure under load. I use 5 sec intervals for my measurements, other values may fail also, but I have neither tested nor observed any failures other than with the value of 5.

Version-Release number of selected component (if applicable):

RHEL6.3-20120427.n.0_nfs-Server-x86_64 installed on HP blade (BL460c G5)

How reproducible:

Variable. Sometimes it will fail several times in a row, other times I can run for an hour before seeing a failure.

Steps to Reproduce:
1. Machine is idle
2. run "vmstat 5"
3. If there is no immediate failure, cycle a load on the box with periods of no activity.
  
Actual results:

vmstat stops with "Floating point exception"

Expected results:

vmstat continues running

Additional info:

Box exhibiting failure: mrg42.

This request was evaluated by Red Hat Product Management for inclusion in the
current release of Red Hat Enterprise Linux. Because the affected component is
not scheduled to be updated in the current release, Red Hat is unfortunately
unable to address this request at this time.  It has been proposed for the next
release. If you would like it considered as an exception in the current
release, please ask your support representative.

Hello Kim.

This is very probably a duplicate of Bug 819073, Bug 820507 and Bug 696202.
I'm closing this one.

If you believe it isn't a duplicate, then don't hesitate to reopen.

Thank you.

Regards,
Jaromir.
