I have a daemon process that runs forever (almost). Something is killing it with a signal 6, but no core dump is done. If I manually kill it with kill -6, then the log message shows core dumped and a core file is created. The process has no reference to SIG_ABRT, so I suspect the kernel is doing the kill and is overriding the core dump. I have previously encountered a similar issue where swap space was running out and the kernel killed this process without a core dump. In that case there were quite a few messages logged about swap space issues before the process was killed. There are no swap messages logged this time.
/crash is a directory in the root file system.
Other than swap issues, when would the kernel kill a process without a core dump?
