I had exactly the same problem with our 11/45 running vanilla V7 uucp.
It seems that the uuxqt.c author left out an fclose()!
Files keep getting opened without being closed and you run out of
file descriptors (which for most systems is 20)!  After much tracing,
I found where the missing fclose() should go.  A program segment
of uuxqt.c follows:

	.
	.
	.
		}
	rmfiles:
		xfp = fopen(xfile, "r");
		ASSERT(xfp != NULL, "CAN'T OPEN %s", xfile);
		while (fgets(buf, BUFSIZ, xfp) != NULL) {
			if (buf[0] != X_RQDFILE)
				continue;
			sscanf(&buf[1], "%s", file);
			unlink(file);
		}
		fclose(xfp);	/* Added forgotten fclose() */
		unlink(xfile);
	}
	.
	.
	.

Uuxqt now merrily processes the hundreds of news articles we receive
in a day.
