It runs on debian squeeze 64bits lts it is built from sources with the fix from ITS#8330 Since the upgrade, it keeps crashing regularly (I would say once every 2 to 5 days) However, there isn't anything in the logs: no message, no error, no nothing slapd no longer runs, I restart it, and it runs ok until the next crash now I don't know how to debug that. (...) What are your advice to track down the cause for the crash?Check whether openldap has been built with --enable-debug=yes. If so set ulimit -c unlimited, which hopefully will create a core dump on a crash. -Dietervery interesting. Yes it is compiled with enable-debug I have just enabled core dumpsaccording to the internet (tm) [grin], this is how I get a stracktrace, right?gdb --core /path/to/THECOREDUMP <<<"thread apply all bt full"
re- it seems that this command is better: gdb /usr/sbin/slapd -c /path/to/core <<<"thread apply all bt full" to associate the core with the program that generated it can someone experienced confirm this?also, in your experience, in case of a crash, can the debugging packages (i.e. slapd-dbg and libldap-dbg on debian) be installed a posteriori to enable better traceback informations?
thanks again for any help. regards, Jephté CLAIN
thanks! regards, Jephté
