When this happens, what's in the lock directory on both machines? Is the system locked?

What's in the queue? uustat? There doesn't seem to be any data sent.

The uucico processes apparently never die. They stay alive and, according to strace, they loop over:

getppid() = 2980
rt_sigprocmask(SIG_BLOCK, [CHLD], [], 8) = 0
rt_sigaction(SIGCHLD, NULL, {SIG_DFL, [], 0}, 8) = 0
rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
nanosleep({1, 0}, 0xbfcb280c) = 0
getppid() = 2980
rt_sigprocmask(SIG_BLOCK, [CHLD], [], 8) = 0
rt_sigaction(SIGCHLD, NULL, {SIG_DFL, [], 0}, 8) = 0
rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
nanosleep({1, 0}, 0xbfcb280c) = 0
getppid() = 2980
rt_sigprocmask(SIG_BLOCK, [CHLD], [], 8) = 0
rt_sigaction(SIGCHLD, NULL, {SIG_DFL, [], 0}, 8) = 0
rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
nanosleep({1, 0}, 0xbfcb280c) = 0

The call seems to work (except the error mesage about system locked):

uucico aetius - (2013-11-02 18:37:53.95 31129) Calling system aetius (port UUCPoverSSH-aetius)

uucico aetius - (2013-11-02 18:38:03.18 31129) Call complete (1 seconds 0 bytes 0 bps)

But uuxqt is never called even if there is mail. Running uuxqt manually works fine and the mail is processed.

I can kill the processes only with kill -9. Even if I kill them all, the problem continues.

Nothing in the Debug file, even when I run uucico with -x9

This setup worked flawlessly for a long time and stopped workng after upgrading to Ubuntu "Saucy Salamander" release.

Ubuntu "saucy salamander" release
Linux kernel 3.11.0
Taylor UUCP 1.07
