mysqld-nt dont' release memory

[jcarneir]

Hi,

I have a mysql database (v5.1) on xp.

I run:
a) pass through querys (from access)
b) php scripts via window's scheduled tasks
c) queries with the query browser

The mysqld-nt process increases the ram usage but dont't release any memory when the queries or tasks have finished.

I need to manually stop and start the service from the mysql administrator. If I can't, eventually, the pc will crash.

Any idea?
thx
