On the SMP Server I play on, I've built a small overworld Pigmen/gold farm, but when it's ignited it doesn't spawn any Pigmen. It's 4 - 23x23 portals in a box, with 10 - 21x23 portals within it.
I built the same design in single player and it spawns pigmen at a decent rate (1 or 2 every 5-10 seconds)
In multi-player it has never spawned even one.
I've asked and the server was not modified to prevent pigmen from spawning, and I know there are at least 2 other farms on the server that work.
Other Details:
The server, and my offline single player tests were in version 1.7.2
I've activated/deactivated the portals several times, over several days.
My entity count is as low as 1/20 (overworld and nether near exit portal)
The server has 50-60 people on, but I've tried when there were only 15.
well it could be a few things 1 being someones allready got all the enitys loaded on the server or 2 there could be some kind of protection plugin in place thats stoping mobs from spawning

Am I overlooking something?

I believe it is, yes. (I don't know what Bukkit is, but it shows up in the help menu)
