would anyone have suggestion as to what could cause errors such as (from dmesg)

Mar 9 22:18:00 uk1upvapmur060 genunix: [ID 457380 kern.notice] NOTICE: core_log: mx[16500] core dump failed, errno=30: /var/coreloc/core_uk1upvapmur060_mx_22815_1007_1362867480_16500

Mar 9 00:29:01 uk1upvapmur056 genunix: [ID 457380 kern.notice] NOTICE: core_log: mx[8941] core dump failed, errno=13: /var/coreloc/core_uk1upvapmur056_mx_22815_1007_1362788941_8941

the issue is that the target location is accessible. It can be read. there are some cores there.

any help or suggestion really appreciated.

    According to intro(2):

    30 EROFS Read-only file system

    An attempt to modify a file or direc-
    tory was made on a device mounted

    13 EACCES Permission denied

    An attempt was made to access a file
    in a way forbidden by the protection

    It looks to me as though /var/coreloc was a read-only file system at 22:18:00. The next error message indicates that something changed but it's still not writable. Perhaps there's an NFS file system mounted at /var/coreloc and it is not exported in such a way that it is writable by root.

    You posted this question in the zones forum. Is there a reason that you suspect something specific to zones is to blame or were you just having problems finding the right forum?

    Check with "coreadm" the location of the core files. Make sure that the directory exist and has read/write permissions.
