What exactly do you mean by round-robin?
Do yo want to rotate the log file every 10 MB (like create a log1, log2, log3, each with a max size of 10 MB)?
Or, do you only want to keep the last 10 MB of the jstack output?

ncalogd.conf

ncalogd.conf(4) 						   File Formats 						   ncalogd.conf(4)

NAME

       ncalogd.conf - NCA logging configuration file

SYNOPSIS

       /etc/nca/ncalogd.conf

DESCRIPTION

       The ncalogd.conf is used to configure Solaris Network Cache and Accelerator ("NCA") logging. The file contains two fields, key and value.

       The status key is used to indicate if the user wants to have NCA logging turned on. If the value of status key is enabled, then NCA logging
       will be turned on. If the value of the status key is disabled, then NCA logging will not be invoked. The default value is disabled.

       The logd_path_name key specifies the absolute pathname of the log file. The log file must be a raw device without a filesystem or a file on
       a  local file system. The default value is /var/nca/log. logd_path_name can also contain a whitespace-delimited list of values for multiple
       log files to a maximum of 16. If you specify multiple log files, you must enclose the list in quotation marks ("). With multiple files, NCA
       logging moves to the next file on the list once the file size specified by logd_file_size has been reached. When the last file is full, NCA
       logging rotates back to the first file in the list. A pointer to the current log file is stored in /var/nca/current.

       The logd_file_size key specifies the value of the file size, in bytes, allowed for each log file specified in by  the  logd_path_name  key.
       The default value is 1000000 bytes.

       In order to implement changes to the ncalogd.conf file, you will need to stop and start NCA logging or reboot.

       NCA stores logs in a binary format. Use the ncab2clf(1) utility to convert the log from a binary format to the Common Log File format.

EXAMPLES

       Example 1: A Sample ncalogd.conf File

       The following is a sample ncalogd.conf file that specifies three log files:

       #
       # NCA Log Daemon Configuration File
       #

       status=enabled
       logd_path_name="/var/nca/log1 /var/nca/log2 /var/nca/log3"
       logd_file_size=1000000

       Note that there is no NCA logging daemon. Logging is performed as one of the functions of the NCA software.

FILES

       /etc/nca/ncalogd.conf	       Lists configuration parameters for NCAlogging.
