I have added configurations in /etc/security/limits.conf * soft core unlimited root soft core unlimited
then after, i have given a process crash, kill -s SEGV <mysql_id>. I got a core dump file for mysql. But after this if i start the service by "service mysql start"(service is getting start). Then if I give crash i'm not able to get core dump file and I have checked "ulimit -c" which is 0. why is it happening? In the same case instead of "service mysql start" if I give "service mysql restart", then if I give crash i'm able to get core dump file. As a workaround i have added "ulimit -c unlimited" to "start" section of /etc/init.d/mysql, then the core dump file is created in both the scenarios. But how to configure "ulimit -c unlimited" in the "start" section of each and every service that is present in /etc/init.d(like prescript before executing start) . Or is there any way to resolve this. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pam in Ubuntu. https://bugs.launchpad.net/bugs/65244 Title: ulimits not set according to /etc/security/limits.conf for root - update documentation Status in “pam” package in Ubuntu: Fix Released Bug description: Binary package hint: libpam-modules Hello, I am desperately trying to allow root big or unlimited coredumps. I set "* soft core 102400" and "* hard core 102400" in /etc/security/limits.conf to no avail, after root login over ssh, I still get the stubborn answer "# ulimit -c" → "0". I don't know if this is a bug in pam itself; it works OK for other users. I also tried to add pam_limits.so to /etc/pam.d/common-session, nothing happens. The same result when putting "ulimit -c unlimited" into /etc/environment. If this is not a bug in PAM but only my inability to find the right solution, please consider it a documentation bug report.
