[comp.mail.uucp] Dual model 83 UUCP dies on big files

rs@eddie.MIT.EDU (Robert E. Seastrom) (08/05/89)

We've got a Dual Model 83 that we're trying to get a mail feed going on.
Since we're a local call away from UUnet, we figured we'd get a feed from
them.  We keep dying on the "Welcome to UUNET" message that they send out
to new subscribers.  As near as I can tell, here's what's happening:

1) UUnet calls us, logs in, and the uucico starts.
2) File transfer goes normally for a while, then stops for ~30 seconds,
   then starts up again.
3) #2 repeats itself a few times.
4) Connection dies.  We always get precisely 9728 bytes transferred.

I had a friend who has a Unix machine send me a test file of approximately
20K.  Same thing happened, except with a different amount getting through.
Here's an excerpt from the AUDIT file (we were running in -x9 mode)

send 46
rec h->cntl 37777777671
send 47
rec h->cntl 37777777601
send 40
alarm 1
send 40
rec h->cntl 37777777611
send 41
rec h->cntl 37777777621
send 42
rec h->cntl 37777777631
send 43
rec h->cntl 37777777641
send 44
rec h->cntl 41
state - 30
rec h->cntl 37777777651
send 45
...

It appears that the problem is on our end, since we keep running into
the same problem with different machines.

An excerpt from /usr/spool/uucp/LOGFILE :

uucp uunet (8/4-17:2-335) OK (startup)
uucp uunet (8/4-17:2-335) REQUESTED (S D.uunetBLuw2 D.uunetSLuw2 daemon)
daemon uunet (8/4-17:8-335) CAUGHT (SIGNAL 1)

It appears that we are hanging somehow, and UUNET is hanging up on us.

Our configuration is as follows:

Dual Model 83, Ver. 7 Unix (Release M1.50), Modem is Bell 212-LIA (genuine
Bell).  The modem appears to be functioning perfectly for interactive
use via a terminal, etc...

Any suggestions?
