I see in some cisco switches that vlans in trunk port misses frequently.what must be the reason behind this??

Can you provide more information?
For example:
If you are referring to something like:
show run int fa 0/1 giving the following output:
interface fastethernet 0/1
switchport mode trunk
vs
interface fastethernet 0/1
switchport mode trunk
switchport trunk allowed vlan 1,25,200
or are you referring to something like show vtp status or show spanning-tree output.
