i am running mysqlrepair on 80G myisam table.

[Joey L]

i am running mysqlrepair on 80G myisam table.
It is taking forever to repair - i am getting a lot of  "Waiting for
table" messeges when i execute "show full processlist"

613 | p_040912   | localhost | p_040912    | Query   |   24 | Waiting
for table | SELECT `oldurl`, `newurl


Can anyone help for this ? is there anything i can tweak in the my.cnf
file that avoids this issue - it is taking forever !!!
thanks
