It worked!I wrote fs.suid_dumpable=1 in /etc/sysctl.conf, `sysctl -p` and restarted dirsrv. Now it dumps.
Thank you! I will report here the backtrace when it occurs. Regards, Dael Maselli. On 07/09/10 19.44, Ulf Weltman wrote:

It seems random, but I can simulate a crash with kill -QUIT. I tried killing a simple `sleep 10`: # ulimit -c unlimited # sleep 10& [1] 19726 # kill -QUIT 19726 [1]+ Quit (core dumped) sleep 10 # ls -l core.* -rw------- 1 root root 290816 Aug 31 08:52 core.1008 But if I kill -QUIT ns-slapd no file is created.ns-slapd typically runs as setuid to a non-root user. Check what fs.suid_dumpable or kernel.suid_dumpable are set to.Thanks, Dael Maselli.-- 389 users mailing list 389-users@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/389-users
