At 6:18 AM -0700 9/21/05, Alan Saul sent email containing:
My POP server stopped working at midnight. My client (Eudora) can't
connect to it, and the monitor window occasionally shows "System
Error -39". The log reads, for example:

The mailbox file is corrupted. A -39 error is an end-of-file error,
that is, the file system read operation reached the end of the file
prematurely. There should be more file there but there isn't.

I don't want this to sound harsh, but I think that's all wrong.

The fact that we see a level 5 message there indicates that this is all the logging there is, and there's nothing here indicating ANY attempt to log in or even any data at all from the client. SIMS has no idea what account is involved.

Note that a TCP connection is usually treated as a flavor of 'file' (i.e. a sequential stream of bytes) so when it ends unexpectedly, a -39 'unexpected end of file' error code is appropriate.

01:22:26 3 POP-066([192.168.1.1]) Send failed: aborted

SIMS tried to send the greeting message to the just-opened connection, but failed.

01:22:26 5 POP-066([192.168.1.1]) *Status=5
01:22:26 3 POP-066([192.168.1.1]) Reading Failed. Error Code=-25010. Read:

-25010 is SIMS-ese for "dropped connection"

See? Reading the mailbox file failed. I'm betting that deliveries to
this account fail as well, yes?

Best course is to probably delete and recreate the account.

I think not.

This looks like either a client problem or a badly hosed TCP/IP stack on the server. If it is happening from more than one client machine, I think a reboot of the server is in order.
