We are seeing an error like 

09-29 01:51:06.993   212   688 I Gecko   : [Parent 212] WARNING: Message requires an excessive number of descriptors channel:957bb000 message-type:-1 header()->num_fds:10779 num_fds:0 fds_i:0: file ../../../../../../../../gecko/ipc/chromium/src/chrome/common/ipc_channel_posix.cc, line 571

in logcat logs. 

Any ideas on it ?

I don't know.  message-type being -1 sounds bad.

This and bug 1074419 might be same root cause then since they have same message in log.

Possibly.

And since Bluetooth appears to post tasks on the IPC thread as in

http://dxr.mozilla.org/mozilla-central/source/dom/bluetooth2/bluedroid/BluetoothSocket.cpp#372

I think it is highly likely.

Blocking on this due to impact of CAF FC release. I hope it turns out to be a DUP. We will resolve this as such once CAF provides feedback after trying bug 1074419
