NAT stucks

Sometimes (a couple of times each day) NAT (PAT) stops translating SMTP
services while translating other services like telnet and HTTP. When
this happens I clear ip nat translation * and every thing works
properly.

I use a 3640 with IOS 12.0(5)

I did a show ip nat translation and got 606 lines of translations report
with 206 like this:

--- 148.206.5.137 10.119.1.65 --- ---
--- 148.206.5.137 10.119.1.65 --- ---
--- 148.206.5.137 10.119.1.65 --- ---
--- 148.206.5.137 10.119.1.65 --- ---
--- 148.206.5.137 10.119.1.65 --- ---
--- 148.206.5.137 10.119.1.65 --- ---
--- 148.206.5.137 10.119.1.65 --- ---
--- 148.206.5.137 10.119.1.65 --- ---
--- 148.206.5.137 10.119.1.65 --- ---
--- 148.206.5.138 10.119.16.134 --- ---

and did a show mem with this header:

               Head Total(b) Used(b) Free(b) Lowest(b)
Largest(b)
Processor 60FD9E20 12739040 4548268 8190772 168392
8105984
      I/O 1C00000 4194304 2014528 2179776 2078924
2106652

What is wrong?
Why do I keep all this translations alive?

show ip nat tranalation verbose give me a lot of:

create 00:08:39, use 00:08:34, left 23:51:25,

TIA
