[asterisk-dev] No Core Dumps

[Steve Davies]

A classic issue which bit me a few weeks ago was that the permissions on
the core dump directory changed, preventing asterisk from creating a file?

Also, check the contents of the kernel sysctl that specifies the filename
of core dumps - If it contains an absolute path, it will override
asterisk's settings.

# cat /proc/sys/kernel/core_pattern
core.%e

Worth a check?
