Accessing printing properties for some drivers causes excessive load on CPU

Bug Description

Binary package hint: samba

When accessing printing properties for some drivers (Xerox and HP Designjet) the load on the CPU goes way up (90%). There is a latency of 30 to 60 seconds during this time. Other drivers (Ricoh) do not exhibit this behaviour.

This has been observed on versions of Samba <= 3.0.28 .

Peter,

We had discussed this on IRC and it appeared this might be the same as upstream bug https://bugzilla.samba.org/show_bug.cgi?id=5372; but a closer examination shows that the upstream fix is only for the "Printers and Faxes" page, not the property pages for individual printers. So I'm afraid I have to conclude that this is not the same bug,

I also can't find any other bugs referenced in the Samba 3.0.x changelogs that would fit this description, so I'm afraid we don't have an SRU candidate here at this point. I can try to track this down in the Samba 3.0/3.2 commit history later, but a concrete pointer from upstream would be helpful.

Darn it. I don't suppose you know what Jeremy Allison meant by this post:

Nope. I've reviewed all the 3.0.x changelogs subsequent to 3.0.28a, and see no mention of a corresponding fix; and the delta to 3.2 is significant so it will take some time to track this down (once I have time available) without a more precise pointer.

As no-one replied for almost 2 years, I am assuming the problem is gone. Therefore, I'll close this report.
