coredump - Linux unable to create core dump from application -

i have 2 servers running vendor application. on 1 server if app crashes creates core dump second not.

the servers supposed set same trying figure out why application doesn't create core dump. i've checked typical settings , have been doing research no luck.

the strange part if run kill -s sigsegv $$ app user, generates core dump in same directory app supposed create core dump. vendor , linux group both unsure @ moment why i'm looking here help.

$ cat /proc/sys/kernel/core_pattern core  $ cat /proc/sys/kernal/core_uses_pid 1  $ ulimit -c unlimited  $ cat /etc/security/limits.conf | grep core *   soft    core    unlimited *   hard    core    unlimited  $ cat /etc/profile | grep ulimit ulimit -c unlimited > /dev/null 2>&1  $ cat /proc/sys/fs/suid_dumpable 0  $ cat /etc/sysconfig/init | grep core daemon_corefile_limit='unlimited' 

there several other reasons why coredump not created. check list of possible reasons in core(5): http://linux.die.net/man/5/core

check dmesg output.

check specific process corefile size limit in /proc/pid/limits.

check if process user can create file of typical coredump size in /proc/pid/cwd directory.

specify absolute file path in /proc/sys/kernel/core_pattern, pointing known writable location.

create short program adhering coredump-accepting protocol, saving somewhere, , specify in /proc/sys/kernel/core_pattern, according core(5). coredumps piped programs not subject limits.
