https://bugzilla.balabit.com/show_bug.cgi?id=258 Summary: syslog-ng 3.4.2 stalls on Ubuntu 12.04 Precise with /var/log full Product: syslog-ng Version: 3.4.x Platform: PC OS/Version: Linux Status: NEW Severity: major Priority: unspecified Component: syslog-ng AssignedTo: bazsi@balabit.hu ReportedBy: carl.chenet-ext@cloudwatt.com Type of the Report: bug Estimated Hours: 0.0 Hi, We had several cases of frozen KVM virtual machines running Ubuntu 12.04 Precise with syslog-ng 3.4.2 taken from madhouse Debian repository. Issue: the servers are not reachable any more. You can initiate a ssh/console connection but the connection freezes before displaying the banner. Each time the /var/log lvm file system is full. The following errors occur in /var/log/system.log : Oct 30 07:05:18 s-metcld-0002 syslog-ng[8467]: I/O error occurred while writing; fd='16', error='No space left on device (28)' Oct 30 07:06:18 s-metcld-0002 syslog-ng[8467]: I/O error occurred while writing; fd='16', error='No space left on device (28)' Oct 30 07:07:18 s-metcld-0002 syslog-ng[8467]: internal() messages are looping back, preventing loop by suppressing all internal messages until the current message is processed; trigger-msg='', first-suppressed-msg='I/O error occurred while writing; fd=\'16\', error=\'No space left on device (28)\'' Oct 30 07:08:18 s-metcld-0002 syslog-ng[8467]: I/O error occurred while writing; fd='16', error='No space left on device (28)' Oct 30 07:09:18 s-metcld-0002 syslog-ng[8467]: I/O error occurred while writing; fd='16', error='No space left on device (28)' Oct 30 07:10:18 s-metcld-0002 syslog-ng[8467]: internal() messages are looping back, preventing loop by suppressing all internal messages until the current message is processed; trigger-msg='', first-suppressed-msg='I/O error occurred while writing; fd=\'16\', error=\'No space left on device (28)\'' Oct 30 07:11:18 s-metcld-0002 syslog-ng[8467]: I/O error occurred while writing; fd='16', error='No space left on device (28)' Oct 30 07:12:18 s-metcld-0002 syslog-ng[8467]: I/O error occurred while writing; fd='16', error='No space left on device (28)' Oct 30 07:13:19 s-metcld-0002 syslog-ng[8467]: internal() messages are looping back, preventing loop by suppressing all internal messages until the current message is processed; trigger-msg='', first-suppressed-msg='I/O error occurred while writing; fd=\'16\', error=\'No space left on device (28)\'' Oct 30 07:14:19 s-metcld-0002 syslog-ng[8467]: I/O error occurred while writing; fd='16', error='No space left on device (28)' Oct 30 07:15:19 s-metcld-0002 syslog-ng[8467]: I/O error occurred while writing; fd='16', error='No space left on device (28)' Oct 30 07:16:19 s-metcld-0002 syslog-ng[8467]: internal() messages are looping back, preventing loop by suppressing all internal messages until the current message is processed; trigger-msg='', first-suppressed-msg='I/O error occurred while writing; fd=\'16\', error=\'No space left on device (28)\'' Oct 30 07:17:19 s-metcld-0002 syslog-ng[8467]: I/O error occurred while writing; fd='16', error='No space left on device (28)' Workaround: We have the mcollective client installed on each server so we were able to kill the syslog-ng process by mcollective. when syslog-ng is killed, the system stops freezing immedialty, the ssh connection is back. I'm not sure to understand how syslog-ng freezes the system but it is worth reporting I guess.
