Bug#472180: Bug #472180: Xprt hogging CPU
Here is the top of a gprof analysis. I'm wondering if the Xkb references indicate that it is the problem. I can hypothesise that some changes in the general Xserver code touched upon Xkb, expecting the DDX to initialise it appropriately. Since Xprint does not use Xkb, it doesn't handle it in any explicit way. Could Xkb be spinning, waiting for the Xprint DDX to tell it to go away and stop being annoying?

Bug#472180: Xprt hogging CPU.
Not 100% sure that I do...! Think it's one of those things that ends up auto-installing. That said, I haven't tried using my printer with it turned off. So, when I said requests, what I actually meant is servicing the Xprt process... No requests are actually being made to Xprt Gavin -Original Message- From: Julien Cristau [mailto:[EMAIL PROTECTED] Sent: 22 March 2008 15:34 To: Gavin Bravery; [EMAIL PROTECTED] Subject: Re: Bug#472180: Xprt hogging CPU. severity 472180 grave kthxbye On Sat, Mar 22, 2008 at 14:33:04 +, Gavin Bravery wrote: On starting the xprint service, the CPU climbs to 100% and sits there.

Bug#472180: Xprt hogging CPU.
Package: xprint
Version: 2:1.4.99.901-1
Severity: serious
--- Please enter the report below this line. ---
On starting the xprint service, the CPU climbs to 100% and sits there.
Most of the time is being spent processing the Xprt requests.
An strace on the process shows repeated messages like this:
clock_gettime(CLOCK_MONOTONIC, {129271, 124564461}) = 0
select(256, [0 1], NULL, NULL, {0, 0}) = 0 (Timeout)
clock_gettime(CLOCK_MONOTONIC, {129271, 124730486}) = 0
select(256, [0 1], NULL, NULL, {0, 0}) = 0 (Timeout)
The only way to return the system to useability was to kill the process
off.
