So, today had an experience w/ a runaway nx client that wrote 44 gigs to
~/.gnomerc-errors in a matter of minutes.
Presumably the uniq -c approach from the prior comment would have
prevented that, although I don't know if there's a handy wrapper layer
in between. I believe the client had a direct handle to the error file.
Just thought I'd mention in terms of sucking up disc space.

Title:
Request to limit xinit writes to .xsession-errors to some reasonable
value, such as 10 megs
Status in “gdm” package in Ubuntu:
New
Bug description:
Binary package hint: x11-apps
Recently, I discovered a system that had been completely shut down for a
rather ridiculous reason.
Over a period of 21 hours, a user's .xsession-filled with the following:
============================
Starting Oracle Universal Installer...
Checking installer requirements...
Checking operating system version: must be redhat-4, redhat-5, SuSE-9 or
SuSE-10 Passed
All installer requirements met.
Checking Temp space: must be greater than 400 MB. Actual 384320 MB Passed
Checking swap space: must be greater than 512 MB. Actual 7730MB Passed
Checking monitor: must be configured to display at least 256 colors Failed
<<<<
>>> Could not execute /usr/X11R6/bin/xdpyinfo
Checking if CPU speed is above 300 MHz. Actual 2992 MHz Passed
Some optional pre-requisite checks have failed (see above). Continue?
(y/n) [n] Continue? (y/n) [n] Continue? (y/n) [n] Continue? (y/n) [n]
Continue? (y/n) [n] Continue? (y/n) [n]
... repeat that last portion about 20 billion times, approximately
256,000 repetitions of the phrase per second, until:
# ls -lh .xsession-errors
-rw------- 1 1000 1000 373G 2010-08-26 13:11 .xsession-errors
Now. I have looked into the history of this, and I've noted that this
sort of thing happens periodically. Users file a bug, and it is
closed.
Now, I'm aware that this is obviously the fault of misbehaving apps...
But.
Is there any reason this couldn't be mitigated?
I've read elsewhere that right now the syntax for this file is xinit calling:
exec >"$ERRFILE" 2>&1
Could that not be changed to:
exec 2>&1 | head -c 5000000 > "$ERRFILE"
Or something similar?
Thanks!
