Lock wait timeout

I'm getting a Lock wait timeout exceeded error and I'm not sure why. I've
been trying to read this SHOW ENGINE INNODB STATUS output, but I don't
understand what it's trying to tell me.

Can someone give me a hand here?

---TRANSACTION 1942A27B, ACTIVE 124 sec, process no 4849, OS thread id

This is the very first statement in a series of statements, so i'm not quite
sure why it would fail. I could understand a later statement failing due to
this one having the table locked or something.
