Hi Keith,
Server mode is an option in Qpopper that is independent of how it is
invoked. It controls certain behavior regarding copying of spool
files. Similarly, fast IO is another Qpopper option. These options
can be set at configure or compile time, or at run time using
command-line flags or system-wide or per-user configuration files.
The Qpopper Administrator's Guide has much more detailed descriptions
of these options. My suggestion would be to try explicitly turning
these off using command-line flags or preferably (because it happens
later) a system-wide configuration file, and see if the problem still
occurs.

Hi Keith,
It sounds very much like what happens when two processes are trying to write
the file at the same time, which may result from a failure in the locking
protocol (e.g., the processes don't agree on the locking mechanism).
- Are you running in server mode?
- Do you have other processes that might access the spool (e.g., an IMAP
server, users accessing the spool directly, etc.)?
- Do you have fast IO or locking options set?
- Did you install your own local delivery agent?
- If you are using server mode, you might try disabling it, more as a
diagnostic than a fix, to see if that stops the problem.
Hi Randy,
1 - No, not running in server mode - Qpopper is invoked by xinetd.
2 - Nothing else should access the spool. Occasionally group users
that share a mailbox log in to check mail but there is always a pop
lock error at that time, so I assume the lock should prevent a
problem?
3 - Fast I/O / Locking options - do you mean at a hardware level (e.g. RAID?)
4 - I have a procmailrc file that directs the delivery into the user's
home directory as ".mail"
