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.

Red Hat Product Errata RHBA-2011:1569 0 normal SHIPPED_LIVE matahari bug fix and enhancement update 2011-12-06 00:39:06 UTC

Description Dave Johnson 2011-08-17 16:30:09 UTC 
Description of problem:
=================================
Noticed that you can start multiple instances of the same agent on a box, we probably should prevent that. 

Version-Release number of selected component (if applicable):
============================================================
v0.4.2-6

How reproducible:
===================
100%

Steps to Reproduce:
1.  install matahari agent
2.  /etc/init.d/matahari-<agent> start
3.  /etc/init.d/matahari-<agent> start
4.  /etc/init.d/matahari-<agent> start
5.  ps -ef | grep matahari
  
Actual results:
===================
notice multiple instances of the same agent

Expected results:
====================
only on instance

Additional info:
====================
Same thing occurs in libvirt-qmf
Comment 2 Zane Bitter 2011-08-17 17:04:07 UTC 
Note that the preferred way to start a daemon is with "service matahari-<agent> start", since that should ensure a consistent environment.

I can't reproduce this issue on Fedora 15 (haven't tried RHEL).
Comment 3 Andrew Beekhof 2011-08-18 04:35:33 UTC 
Reproduced on RHEL
