Configured to dump cores on /var/db/system/cores/ but none is dumped

[braiam]

I'm trying to track down why or how syslog-ng is core dumping. The message log says it dumped the core, corefile is configured to `kern.corefile: /var/db/system/cores/%N.core`. But I check that directory and there's nothing. Either the message is lying (which I doubt) or the kernel is not dumping correctly. The relevant sysctl variables are:

Code:

kern.corefile: /var/coredump/%N.core
kern.coredump_devctl: 0
kern.nodump_coredump: 0
kern.coredump: 1
kern.capmode_coredump: 0
kern.sugid_coredump: 1
kern.coredump_pack_vmmapinfo: 1
kern.coredump_pack_fileinfo: 1
debug.elf32_legacy_coredump: 0
debug.elf64_legacy_coredump: 0
