Hi all,</div>

We're currently trying to get DiFX working with the following setup: 4-bit, 2 channel (L + R pols), 2 threads (2 subbands), delivered in real time via UDP. It has been working fine up until the point where we tried adding a second thread - single-thread VDIF
has been working for us.<br>
<br>
When running in multi-threaded mode, the datastream processes crash with the following message:<br>
<br>
'vdifmux() failed with return code -2014, likely input buffer is too small!'<br>
<br>
I have managed to trace the problem to a check in 'getLowestFrameNumber' in vdifio/src/vdifmux.c. The inequality check in that function:<br>
<br>
'getVDIFNumChannels(vh) != vm->inputChannelsPerThread'</div>
<div class="elementToProof" style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">

<div class="elementToProof" style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
succeeds as the function returns a value of 2 while 'inputChannelsPerThread' has a value of 1. This happens for every iteration so vdifmux() fails and returns a -2014 error code.</div>

I'm not sure where to go from here and was hoping someone more familiar with DiFX could help out. Hopefully I'm not missing something obvious! If you need any more information I haven't provided please do ask.</div>
