Per olof You should try setting kern.maxdsize in /boot/loader.conf and then reboot the system. This sysctl sets the maximum data size of a running process you may also have to tune some of the limits using ulimit. The example below sets the max data size to 1.5Gb: kern.maxdsiz="1610612736" Tom ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
