Code for that is here: source3/lib/messages_dgm.c:messaging_dgm_lockfile_create()

        /* no O_EXCL, existence check is via the fcntl lock */

        lockfile_fd = open(lockfile_name.buf, O_NONBLOCK|O_CREAT|O_WRONLY,
        if (lockfile_fd == -1) {
                ret = errno;
                DEBUG(1, ("%s: open failed: %s\n", __func__, strerror(errno)));
                return ret;

        lck = (struct flock) {
                .l_type = F_WRLCK,
                .l_whence = SEEK_SET

        ret = fcntl(lockfile_fd, F_SETLK, &lck);
        if (ret == -1) {
                ret = errno;
                DEBUG(1, ("%s: fcntl failed: %s\n", __func__, strerror(ret)));
                goto fail_close;

        unique_len = snprintf(buf, sizeof(buf), "%ju\n", (uintmax_t)unique);

        /* shorten a potentially preexisting file */

        ret = ftruncate(lockfile_fd, unique_len);
        if (ret == -1) {
                ret = errno;
                DEBUG(1, ("%s: ftruncate failed: %s\n", __func__,
                goto fail_unlink;

Can you extend the DEBUG(1,) message to print out (a) the
filename and (b) the value of unique_len.

I'm guessing you're hitting this (from the Solaris man

The ftruncate() and truncate() functions will fail if:

A signal was caught during execution.
The length argument was less than 0.

Would be my guess...

EFBIG or EINVAL The length argument was greater than the maximum file size.

An I/O error occurred while reading from or writing to a file system.
The named file resides on a read-only file system.
The truncate() function will fail if:

A component of the path prefix denies search permission, or write permission is denied on the file.
The path argument points outside the process’ allocated address space.
The path argument is not an ordinary file.
