| Summary | 0000221: No traceback produced for sd, dir on Ubuntu 12.04 | ||||
| Description | No traceback files are produced for dir and sd on Ubuntu 12.04 standard installation (Ubuntu 10 not tested, yet). Need to check, if this a Bareos problem or if some special settings are needed on Ubuntu. ---- kill dir and see if it can create backtrace ---- ---- killing: kill -SIGSEGV 4203 --- ----- waiting for PID 4203 ------ PID 4203 took 1s to die ----- waiting for /var/lib/bareos/bareos.4203.traceback ---- ------ File /var/lib/bareos/bareos.4203.traceback appeared in 0s ----- BEGIN of /var/lib/bareos/bareos.4203.traceback ---- Could not attach to process. If your uid matches the uid of the target process, check the setting of /proc/sys/kernel/yama/ptrace_scope, or try again as the root user. For more details, see /etc/sysctl.d/10-ptrace.conf ptrace: Operation not permitted. /var/lib/bareos/4203: No such file or directory. ---- kill sd and see if it can create backtrace ---- ---- killing: kill -SIGSEGV 4215 --- ----- waiting for PID 4215 ------ PID 4215 took 1s to die ----- waiting for /var/lib/bareos/bareos.4215.traceback ---- ------ File /var/lib/bareos/bareos.4215.traceback appeared in 0s ----- BEGIN of /var/lib/bareos/bareos.4215.traceback ---- Could not attach to process. If your uid matches the uid of the target process, check the setting of /proc/sys/kernel/yama/ptrace_scope, or try again as the root user. For more details, see /etc/sysctl.d/10-ptrace.conf ptrace: Operation not permitted. /var/lib/bareos/4215: No such file or directory. | ||||
| Steps To Reproduce | # PID: pid of director / sd kill -SIGSEGV $PID Check for traceback file /var/lib/bareos/bareos.$PID.traceback | ||||

Ubuntu has changed default ptrace kernel options, you need to: echo 0 > /proc/sys/kernel/yama/ptrace_scope sysctl before debugging on Ubuntu. Needs documentation in distribution specific section. |
