You mean to say the SQL statements are making this issue ? I also
suspected wrongly formed query statements making this much load on the DB
server.
I also suspect this, as the developers who write queries are not so
expertised for writing optimized queries, needs to be addressed separately.
How can I find out which query statements are making the DB server on its
knees ? Any method to find the bad queries? what parameters/behaviours to
be checked for finding those query statements which really makes the
db server to its knees by the heavy lifting ? any hints most welcome, I
can explore and fix those ones.

Sorry I missed to mention it, this is an EDB 16 server. Eventhoug I
prefer to use any piece of S/W that is FOSS community editions, sometimes
it is demanded to manage these products too.
