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.

Doc Type: Bug Fix
Doc Text:
The previous version of snmpd, the Net-SNMP agent, gathered disk IO and CPU usage statistics for UCD-SNMP::systemStats as 64bit on 64bit systems. Appropriate MIB describes these statistics as 32bit and snmpd reported "truncating integer value > 32 bits" to system log when processing the 64bit values. snmpd in updated packages collects values of UCD-SNMP::systemStats as 32bit integers and thus does not report aforementioned message to syslog. (BZ#681949).

Description Scott Merrill 2011-03-03 16:59:08 UTC 
Description of problem:
We have a RHEL6 x86_64 server onto which we've installed RT, and imported several hundred gigs of email for an audit. We have backed up and restored the RT database a couple times to ensure that backups and restores are successful. As such, we've written and read an enormous amount of data to the SAN volume which holds the database.

We use Zenoss to monitor this server, and during every polling cycle we get the following error in /var/log/messages:

Mar  3 11:49:07 servername snmpd[17720]: truncating integer value > 32 bits

Using snmpwalk we have identified that the error occurs only when querying the following OIDs:
  1.3.6.1.4.1.2021.11.57.0
  1.3.6.1.4.1.2021.11.58.0

Version-Release number of selected component (if applicable):
  net-snmp-libs-5.5-27.el6_0.1.x86_64
  net-snmp-5.5-27.el6_0.1.x86_64
  net-snmp-utils-5.5-27.el6_0.1.x86_64


How reproducible:
Fully reproducible. Every time an SNMP query hits either ssIORawSent or ssIORawReceived the error will be logged.


Steps to Reproduce:
1. snmpwalk -v 1 -c foobar 1.2.3.4 1.3.6.1.4.1.2021.11.57.0
2. snmpwalk -v 1 -c foobar 1.2.3.4 1.3.6.1.4.1.2021.11.58.0
3. repeat the above two commands with -v 2c, too
  
Actual results:
snmpd[17720]: truncating integer value > 32 bits

Expected results:
no error

Additional info:
It looks like this may be related to the following two closed bugs:
  https://bugzilla.redhat.com/show_bug.cgi?id=202584
  https://bugzilla.redhat.com/show_bug.cgi?id=528164

I suspect that a reboot of the server will clear up these errors, and we're not likely to generate this much disk I/O again any time soon, so this is not a critical error; but it seems like the kind of thing that net-snmp should account for properly.
Comment 3 Jan Safranek 2011-03-04 15:25:59 UTC 
I fixed it upstream: http://net-snmp.svn.sourceforge.net/viewvc/net-snmp?view=revision&revision=20061
