Hi All,

Thanks for all the response -- it was all very helpful! I don't want to limit
the my backend processes because each response is consider "important" so
running any backend limitation is consider unaccceptable.  So,  I've increased
the system NFIle limit.. so far so good :-)

Are they any way to pool connections through a single backend process?

thanks,
Thanh
