[LAU] jackd terminates on its own

[jonetsu]

When using the latest Bitwig and loading several projects, enabling
audio for each one, playing it for a few seconds then loading another
one, playing it, so on so forth, jackd will steadily terminate, like
this:

Jack: JackPosixProcessSync::TimedWait time out = 116080
Jack: JackPosixProcessSync::TimedWait finished delta = 3668.0
Jack: JackEngine::ClientExternalClose ref = 2
Jack: JackEngine::ClientCloseAux ref = 2
Jack: JackEngine::ReleaseRefnum server quit
Unknown error...
terminate called after throwing an instance of
'Jack::JackTemporaryException' what():  



This is steady behaviour.  On the Bitwig side the following will be
seen:

[2017-06-23 18:17:10 ramona-server error] Connection broken with
client: java.net.SocketException: Socket closed



jackd is 1.9.10+20150825git1ed50c92~dfsg-1ubuntu1

Bitwig is 2.1.1

Is there a fix for this ?

Thanks.
