Thanks Phoenix

zmloggerctl stop (if this is not done, "1 client is using or hasn't closed the table" errors are given on next step, this seems normal to me)

/opt/zimbra/mysql/bin/myisamchk -s /opt/zimbra/logger/db/data/zimbra_logger/*.MYI
(returns nothing - "no repair needed" messages suppressed)

So it seems the logger tables are all ok. I can see that there is data in them as well (`select * from raw_logs limit 1` returns a very recent log entry)

Tried on a different client machine to access the admin gui and same error is returned.

find /opt/zimbra/logger/ -name *.err returns nothing, so there doesnt seem to be an error file as mentioned in a few posts.
