>zmcontrol -v
Release 5.0.18_GA_3011.RHEL5_20090707164432 RHEL5 FOSS edition

A few days back the daily reports stopped working. I haven't updated any components. No major/minor changes in the server either.

Executing this
>/opt/zimbra/libexec/zmdailyreport -m

i get the result as

DBD::mysql::st execute failed: Table './zimbra_logger/mta' is marked as crashed and last (automatic?) repair failed at /opt/zimbra/libexec/zmdailyreport line 506, <CONF> line 340.

The Server Status on the console shows the data is stale besides the current date & time.

Can you please guide me to the right direction, as to, how should i make the daily reports work again.
