su on 10.2: TERM: Undefined variable
I noticed some weird behavior of "su" command in shell scripts running from cron after upgrade from FreeBSD 8.4 to 10.2. If I have this in script su -m www -c 'ls -l' then I get "TERM: Undefined variable" on the stderr if this script is run from cron. It works fine on FreeBSD 8.4 Is it intentional behavior?

I am asks this questions becaus in may case don't see automatic txsync
on poll:
device open as
np->nr_ringid = NETMAP_DO_RX_POLL;
np->nr_flags = NR_REG_ALL_NIC;
rc = ioctl(balancer.inside.fd, NIOCREGIF, np);
poll do as
pollfd[1].fd = thr->inside.fd; pollfd[1].events |= POLLIN;
poll(pollfd, nfd, 1000);
and I don't see output sysncing w/o pollfd[1].events |= POLLIN | POLLOUT;
Only one round packet outputs I see and no slot updates.
