Package: ppp Version: 2.4.2+20040428-6 Severity: critical Justification: breaks the whole system
hello pppeople, i've encountered serious problems with pppd and days of monitoring the issues lead me to the assumption that pppd is to blame. feel free to tell me otherwise and i'll happily forward the problem to the right people - because i am not guru enough to fix it. the problem in short: i am using pppd with pppoe (ADSL dialup) i get disconnected by my ISP once a day and pppd receives "LCP terminated by peer" then. normally pppd will reconnect and the box would be online again. this does not happen anymore, instead 30min after disconnect all RAM is chewed up by *something* (still don't know by what, please read on) and OOM killer kicks in, killing almost every application. i have reported the issue to the linux-kernel mailinglist first, because i thought it was a kernel issue: http://lkml.org/lkml/2005/3/8/173 http://lkml.org/lkml/2005/3/10/109 maybe the replies are noteworthy too. yesterday i hit the issue again, with more (hopefully helpful) details: http://www.ussg.iu.edu/hypermail/linux/kernel/0503.2/0316.html again, the time between "LCP terminated by peer" to the first OOM messages are (alsmost exactly) 30min. when this happens, i am usually not around, so when i get to the machine, OOM has already happened. i can recover the machine (no reboot, but SYSRQ-E) and i have to kill -9 pppd, anything else does not work: http://nerdbynature.de/bits/sheep/2.6.11/oom/pppd.log ("Terminating on signal 15" does not work, "+++ killed by SIGKILL +++" is the only choice.) i first noticed this behaviour with a new kernel, namely 2.6.11, but downgrading to a former (stable for me) kernel (2.6.11-rc5-bk2) did not help. instead, i downgraded from pppd-2.4.3-20041231+2 to ppp-2.4.2+20040428-6 and got rid of the problem! 2.4.3 was uploaded on 26.02.2005, and a couple of days later i switched to a new kernel and did a "apt-get upgrade". that could be the cause, i suspected kernel issues first. have a look at http://nerdbynature.de/bits/sheep/2.6.11/oom/ for further details, feel free to ask. i still did not manage to reproduce the problem "by hand", e.g. by setting up a pppoe server on the same machine, connecting with "pppd call..." and killing the pppoe server (in the hope that it might send "LCP terminated by peer" to the pppd"). thank you for your time, Christian. -- System Information: Debian Release: 3.1 APT prefers unstable APT policy: (990, 'unstable'), (1, 'experimental') Architecture: i386 (i686) Kernel: Linux 2.6.11.3 Locale: LANG=C, LC_CTYPE=C (charmap=ANSI_X3.4-1968) Versions of packages ppp depends on: ii libc6 2.3.2.ds1-20 GNU C Library: Shared libraries an ii libpam-modules 0.76-22 Pluggable Authentication Modules f ii libpam-runtime 0.76-22 Runtime support for the PAM librar ii libpam0g 0.76-22 Pluggable Authentication Modules l ii libpcap0.7 0.7.2-7 System interface for user-level pa ii libssl0.9.7 0.9.7e-3 SSL shared libraries ii makedev 2.3.1-76 creates device files in /dev ii netbase 4.20 Basic TCP/IP networking system ii procps 1:3.2.5-1 /proc file system utilities -- no debconf information -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
