Hi Herbert,

    Thanks for the pomprt reply. I have tried to put all the following
files with
some number (i.e. 2048 for example) to try out.

(BTW, the doc in ulimits section does not mention
supporting of ulimits on core though)

/etc/vserver<guestos>/rlimits/core
/etc/vserver<guestos>/rlimits/core.hard
/etc/vserver<guestos>/rlimits/core.soft

/etc/vserver<guestos>/ulimits/core
/etc/vserver<guestos>/ulimits/core.hard
/etc/vserver<guestos>/ulimits/core.soft

Then I do:
vserver guestos stop
vserver guestos start

I got the same error as "vc_set_rlmit: Unknow error 524) I assume I got this
from the rlimts/core setting.

Then I do:
vserver guestos enter
ulimit -c

(I still got 0 and not the value I set in the ulimits file ?)

Any idea ?

what I was trying to do is to use CLI for customer to setup
their default corefile size in that Vserver during runtime.
The value can take effect after Vserver restart.

Thanks,

Jennifer
