Description Neil Horman 2009-03-31 18:00:32 UTC

Description of problem:
makedumpfile can use a large amount of memory durin goperation.  This is undesireable from both a performance and integrity problem (given that it operates primarily during kdump core capture, which is both a time sensitive operation, and a low memory environment).  It would be beneficial if makedumpfiles memory footprint were minimized

Comment 1 RHEL Program Management 2009-06-15 20:59:18 UTC

This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux major release.  Product Management has requested further
review of this request by Red Hat Engineering, for potential inclusion in a Red
Hat Enterprise Linux Major release.  This request is not yet committed for
inclusion.

Comment 2 RHEL Program Management 2010-02-17 21:45:52 UTC

This feature request did not get resolved in time for Feature Freeze
for the current Red Hat Enterprise Linux release and has now been
denied. You may re-open your request by requesting your support
representative to propose it for the next release.

Comment 3 Neil Horman 2010-03-17 14:51:10 UTC

I'm going to close this for now, given that more recent upstream improvements have allowed users to tune the amount of memory they use with makedumpfile to some degree (the -b option)
