[Mailman-Users] digest delivery

[Sean]

A list on one of the servers I admin is experiencing strange digest
delivery behavior.  digest_send_periodic is set to yes but the digest are
not being sent until the digest_size_threshhold is being reached.
digest_size_threshhold is set to 500Kb so it takes a few days to reach
that.  Any suggestions on what to look at here?

MM is 2.1.5, python is 2.3.4

No other lists have reported problems with digest delivery.

Thanks,
Sean
