Summary: syslog can cause memory shortage condition on /dev
Classification: openSUSE
Product: openSUSE 12.1
Version: Final
Platform: All
OS/Version: Linux
Status: NEW
Severity: Normal
Priority: P5 - None
Component: Basesystem
AssignedTo: bnc-team-screening@xxxxxxxxxxxxxxxxxxxxxx
ReportedBy: jengelh@xxxxxxxxxx
QAContact: qa@xxxxxxx
Found By: Beta-Customer
Blocker: ---


I notice that when /dev/tty10 does not exist (various reasons, ranging from
CONFIG_VT=n or number of ttys limited to less than 10 by changing
MAX_NR_CONSOLES), rsyslog, and possibly other implementations by way of
SUSE-shipped configurations, will nevertheless write something to /dev/tty10,
if need be, creating a regular file. Given that /dev is tmpfs, this means that
this tmpfs will be filled up sooner or later, leading to no new nodes being
able to be spawned in /dev by udev due to ENOSPC.
