Hello,
Each time we run long queries (over around 5 seconds) the mySQL server
fails and restarts (you can see it in the error log that starts with
Database page corruption on disk or a fail.. and then there is a
dump...) and the query return with Lost connection to MySQL server
during query...
Using Linux 9 with mySQL 4.1.11-standard the tables are InnoDB
The error is happening from everywhere: mysql command line, Query
browser, from local and remote computers, running selects, insert and
even check table, EMS client . Java (see below the log)
The problem is probably not in the network parameters, see list of the
variables below
The database is quit big around 5 GB
After the error the server restart automatically and continue to run for
the short queries
We found one place where long queries work - when we run from the query
browser the same select * from some big table. However running
from the same place check table... reproduce the error !. Again
running the same select * from some big table from all the other
palaces cause the server to fall
