Comment 2 RHEL Program Management 2010-09-16 17:38:13 UTC

Thank you for your bug report. This issue was evaluated for inclusion
in the current release of Red Hat Enterprise Linux. Unfortunately, we
are unable to address this request in the current release. Because we
are in the final stage of Red Hat Enterprise Linux 6 development, only
significant, release-blocking issues involving serious regressions and
data corruption can be considered.

If you believe this issue meets the release blocking criteria as
defined and communicated to you by your Red Hat Support representative,
please ask your representative to file this issue as a blocker for the
current release. Otherwise, ask that it be evaluated for inclusion in
the next minor release of Red Hat Enterprise Linux.

Comment 9 Kashyap Chamarthy 2011-04-25 14:51:51 UTC

Note:

After discussion with Ade Lee,

This bug can _only_ be verified when TPS(pki-tps) pkg is available on RHEL 6.1 or above. As this behaviour can only be noticed in TPS subsystem which uses mod_nss to submit POST requests 

Verification procedure:
---------------------------
1/ Install and configure pki-ca, pki-kra,  pki-tks, pki-tps
2/ In TPS Admin Operations -> Advanced Configuration -- Edit and save a TPS profile('userKey') multiple times 
3/ Ensure CPU on TPS machine does not go through the roof.
----------------------------

Comment 10 Kashyap Chamarthy 2011-04-27 09:20:41 UTC

Note: pki-tps pkg is not (yet)available in RHEL6.1

After discussion with Ade, this bug is verified upstream. Turning this to verified.


Rob, I hope there is objection from you as well.
