Pretty annoying problem :( Here's how I enable core dumps on linux installs in sysctl (reboot required): fs.suid_dumpable = 1 kernel.core_pattern = /tmp/core.%e.%u.%t kernel.core_uses_pid = 1
On a live system (no need to restart): echo 1 > /proc/sys/fs/suid_dumpable echo 1 > /proc/sys/kernel/core_uses_pid echo "/tmp/core.%e.%u.%t" > /proc/sys/kernel/core_pattern Hope that now you will be able to "enjoy" the core dumps :-/ Regards, Ovidiu Sas On Sat, Jan 3, 2015 at 4:38 PM, Alex Balashov <abalas...@evaristesys.com> wrote: > Hi, > > I recently had a simultaneous crash on three production instances of > Kamailio.
