Hi John,

Ø  EPICS_CA_MAX_ARRAY_BYTES is set to 100MB on both the server and client sides. 

That is actually not the best practice.  My understanding is that once the CA server needs buffers larger than 16KB it actually allocates buffers of size EPICS_CA_MAX_ARRAY_BYTES.  Thus you should not make it that much larger than it needs to be,

As far as I know there is nothing that ADPilatus can do to cause camserver to write a bad TIFF file.  If the TIFF file written by camserver is bad then I would look on the camserver side.  ADPilatus is just sending simple ASCII commands over a socket to camserver.

On my system I see this when I start camserver on my Pilatus 100K system.

PILATUS 100K, S/N 1-0229, BNL

...Code release: tvx-7.3.13-121212

1 PSI PMC GigaSTaR card(s) initialized

PMC GigaSTaR kernel driver version: gs_drv-2.16

PMC GigaSTaR device no. 0, Version 0x1041a424

So I appear to be running tvx-7.3.13-121212, which is almost identical to your version tvx-7.3.13.121212b.  Yours just has a b at the end.

My Pilatus 100K is running fine with the latest ADCore and ADPilatus.
