BIND stopping/starting - unknown control channel command sync

Hello,

since some days (or a week) I have problems with BIND stopping and restarting - sometimes within minutes. Today BIND stopped and started already 70 times.

The logs show a unknown control channel command 'sync ':

received control channel command 'sync DOMAIN.COM'
unknown control channel command 'sync DOMAIN.COM'
received control channel command 'stop -p'
shutting down: flushing changes
stopping command channel on 127.0.0.1#953
no longer listening on ::#53
no longer listening on 127.0.0.1#53
no longer listening on 127.0.0.2#53
no longer listening on ---.---.---.---#53
exiting
starting BIND 9.8.1-P1 -u bind
built with '--prefix=/usr' '--mandir=/usr/share/man' '--infodir=/usr/share/info' '--sysconfdir=/etc/bind' '--localstatedir=/var' '--enable-threads' '--enable-largefile' '--with-libtool' '--enable-shared' '--enable-static' '--with-openssl=/usr' '--with-gssapi=/usr' '--with-gnu-ld' '--with-geoip=/usr' '--enable-ipv6' 'CFLAGS=-fno-strict-aliasing -DDIG_SIGCHASE -O2' 'LDFLAGS=-Wl,-Bsymbolic-functions -Wl,-z,relro' 'CPPFLAGS=-D_FORTIFY_SOURCE=2'

We assume that it could arise from an Webmin/Virtualmin update which is adressing the new command 'sync' (as we had all updates installed automatically - changed now to security updates only).

BIND version 9.8.1
Webmin version 1.890
Virtualmin version 6.03

Ubuntu Linux 12.04.1
Kernel and CPU Linux 2.6.32-40-pve on x86_64

Has anybody the same problems or give us a hintz how to fix this?
Thanks!
Mars
