Could not lock 'data_monitor' [reason='ilpUdp']

TRUNCATE table 'data_monitor'

hi terry, please see this FAQ item: <https://questdb.io/docs/troubleshooting/faq/#why-do-i-get-table-busy-error-messages-when-inserting-data-over-postgresql-wire-protocol>

TRUNCATE is not INSERT, but it has the same cause.

it seems your ILP client keeps pushing data in.

yes but pushing data into another table not the one i want drop or truncate

are you positive? the error message says the table you are trying to truncate is busy processing ILP messages.

yes i confirm have stop push data into the table i want drop
