rsync - May 2006 - timeout in data send/receive ???

We have two (2) servers on a LAN, backup [A] and tjg1 [B].  We want to
PUSH file synchronization from [B] to [A].  We are repeatedly this
error:

    rsync error: timeout in data send/receive (code 30) at io.c(181)

Google has not been kind; nor have the archives to this list.
Perhaps, I am ignorant of the appropriate search criteria?


There are other interesting facts:

[1] There are ~74 GB of files to be regularly synchronized.

[2] This is on an internal LAN; and we have elected to forgo security
    processes (e.g., ssh).  rsyncd is dynamically started via inetd;
    and this problem is repeatable with a minimal rsyncd.conf, such
    as:

      log file = /var/log/rsyncd.log
      syslog facility = daemon
      pid file = /var/run/rsyncd.pid
      [data]
      comment  = DATA volume archive
      path     = /usr/local/backup/archive/DATA/


[3] Historically, these files resided on a netware server; and another
    process (NOT rsync) has been successfully backing up these files
    to [A].  Now, we want to serve these files from [B].  So, the
    first thing was to rsync these files from [A] to [B].

[4] PULLING from [A] to [B] repeatedly succeeds.

[5] PULLING from [B] to [A] repeatedly succeeds.

[6] Notice that this problem chronically manifests itself when one
    side to this process begins EMPTY.

[7] The problem repeatedly manifests itself _after_ PUSHING ~2 GB of
    files.

[8] Obviously, in production, there will NOT be an empty side to this;
    but, until we understand the cause to these failures, our
    confidence in this process will be less than ideal ;>


What do you think?
