Mob spawners only spawn a limited amount of mobs in a chunk.

I like to build mob traps to get drops and experience. But they don't spawn as much as they used to. There is a limited amount of mobs that come out of the spawner trap and i make sure is that they are not getting stuck anywhere. Please fix.

This is an annoyance, not a bug.

Please be more specific. How limited are they spawning, in comparison to 'how they used to'?

The number of mobs that can spawn are limited by the following:

The block will attempt to spawn 4 mobs at randomly chosen points within the spawning area, then wait anywhere from 200 to 799 ticks (10 to 39.95 seconds) before spawning again. ... Except for spawning on a solid block, all of the usual requirements for spawning must be met (not in a solid block, correct light level, etc.), so the spawner will often produce fewer than 4 mobs. If the block fails to spawn any mobs because it did not pick any suitable locations, it will repeat this process every tick until it succeeds. Only when it manages to spawn at least one mob will it start waiting for the next cycle. If, at the time of spawning, 6 or more monsters of the block's type are present within a 17 × 9 × 17 area (17 wide and 9 high and 17 long), centered on the spawner block, the spawner "poofs" without creating any monsters and then waits for the next cycle. However, if there are more of the mob outside of the specified range, then the monster spawner will continue spawning mobs indefinitely.

The catch is:

if there are 6 or more of the mob type in the 17x9x17 area around the spawner, skip this spawn cycle.

So if you are getting at least 6 then it seems to be within the limitations.

Not really enough information in order to replicate/understand the issue. Review the Bug Report Guidelines Here.
