ArrayBlockingQueue deadlock

Question

So, I'm currently having a producer - consumer system that use ArrayBlockingQueue. All iz well for a long time, but yesterday the system is halting, and when I do jstack over the jvm, I found out that all threads that are supposed to "offer" is in Thread.State: WAITING when offering to the ArrayBlockingQueue, and all threads that are supposed to "poll" is also in Thread.State: WAITING condition when polling from ArrayblockingQueue.

I'm still new in analyzing jstack result, but from my understanding the log produced by jstack is a snapshot of all thread state in jvm. If so, I'm guessing this is a deadlock?

I've tried googling the cause, but can't seem to find anyone talking about deadlock in ArrayBlockingQueue. I also unable to reproduce the problem. Are there any known issue for this particular problem?

this is some log generated by jstack:
