It ran overnight, then crashed again this morning, this time with
--error_level 9. The complete log is 623 MB. The final few lines
below. Let me know if you'd like more from the log (8.6 MB bzip2'ed).
To your questions:
1. The crash in this case seems to be an assert (see log).
2. I'm off site, but I'm pretty sure that I'm using The Link. If not,
it's a DS9097U. Then a USB-to-RS232 adapter. The OS is Linux.

3. owserver is being accessed through owcapi from a program running on
the same computer (accessing localhost:3001). The program has a local
queue to make sure that owserver only receives one request at a time
(used to cause serious trouble if otherwise). On the other hand,
owserver will usually get a new request immediately after finishing
one. There also is a shell script using owget to read one sensor
every 10 minutes (so owserver can get two requests simultaniously, but
this happens so rarely that it doesn't seem to be a problem). It can
occationally use owwrite as well, which happened twice during this
run, several hours before the crash.
