core dump

[Lai Nee Shyang_1]

Hi,

I've a question. When a daemon (eg. nfsd) hang and if it does a core dump, will it be at located at "/" or somewhere else. If there is a directory at root "/core" will this prevent the core dump be written to "/" ?

Thanks

Hi,
Normally core was writen to working directory.

yep, creating a directory named core is an old trick to avoid core dumps.

beware if you automatically remove core dumps to look only for "files" named core
(find ... -name core -type f ....)

Hi,

i've tested this on my test system.
Here is what i get:
If i do a kill -3 it writes a core file at /
With: file /core you get:
core file from 'nfsd' - received SIGQUIT
An yes if i do mkdir /core the nfsd would not write a core file at /
