[one-users] Generating core dump using SIGQUIT

[Manish Sapariya]

Hi Shashank,
Try setting core size to big value, typically its 0.

# ulimit -a
core file size          (blocks, -c) 0

shows you limits of various size. You can set core
file size using

#ulimit -c 999999999999

and using the same shell start oned and then try to
generate the core dump.

Hope this helps.

Thanks and Regards,
Manish
