migracja z mysql 4 do mysql 5

[k4 0]

Witam

 

jakis czas temu zmigrowalem z mysql4 do mysql5, poprzez debianowe apt-get. Na poczatku nie zauwazylem jakiegos wielkiego obciazenia. Jednak od wczoraj baza mi sie zapycha. Nie wiem czego to wina.

 

ZAjetosc dysku mam na poziomie 82%

Czy mam wyswietlic jeszscze jakies dane w celu diagnostycznym ?

Pobieram strone i proces zamiast skonczyc dzialanie dalej uzywa procesora 100% az do momentu az go nie skilluje.

# The MySQL database server configuration file.

# You can copy this to one of:
# - "/etc/mysql/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.
# 
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
#
# For explanations see

# This will be passed to all mysql clients
# It has been reported that passwords should be enclosed with ticks/quotes
# escpecially if they contain "#" chars...

Nie wiem czy to ma sens, ale czy skrypt na końcu ma funkcję mysql_close?
