In fact, we are receiving much more packets that we are able to process in the same time. This is leading to having not a single block free to get new packets and we get stuck in this position.

I don't find any test that avoid getting into this situation.

Shouldn't drop the incoming packets if we can store them inside the structure while processing the already received packets ? I'm working on this part but that's frankly hard to understand the code without any documentation and very very few comments inside the code.

Is there any public svn | git of this project ? Maybe you have some patches on this topic.

Dear All,

I'm been spotting a serious issue we do have in production.

We are running in async mode with a fixed bandwidth and a fec 8x8

If the storage device gets lower than the network bandwith then after a while udpcast locks itself.

I've been enabling the debug and discovered that the free blocks is loosing 1 byte very often (surely links to the FEC).

Once the free blocks is set to 1 the process is totally locks.

Aside this bug, I found that udpcast sends more the same data several time while it got sent once. This is maybe related.

Any thoughts on this ?

Thanks,
