Disconnections from zero clients

Hello:

 

We are on Horizon 6.1.1 using Samsung NC241 zero clients doing a PoC over our local network (no remote users), all going through one connection server with about 20 clients total. We've run in to an issue where some users on the zero clients are getting disconnected at random times while using the session. It seems to be worse for those that are streaming audio/media, than those that are not. Around the time that they are disconnected, their audio streaming will start getting choppy and eventually the session will lock and shortly after they get the disconnect error. After re-connecting, everything will be fine for a few hours.  I have looked at the Teradici client logs as well as the pcoip_server logs.  About the same time that the client drops, the pcoip_server log will truncate and it will start a new log, which tells me that it might be crashing and relaunching?  In the Windows event viewer I'm seeing the error:

 

Faulting application name: pcoip_server_win32.exe, version: 3.30.1.27618, time stamp: 0x5554434e

Faulting module name: svgadevtap.dll, version: 9.9.0.6642, time stamp: 0x55482957

Exception code: 0xc0000005

Fault offset: 0x00006107

Faulting process id: 0x350c

Faulting application start time: 0x01d1496c7163e1e0

Faulting application path: C:\Program Files\Common Files\VMware\Teradici PCoIP Server\pcoip_server_win32.exe

Faulting module path: C:\Program Files\Common Files\VMware\Teradici PCoIP Server\svgadevtap.dll

Report Id: e8fdbad1-b572-11e5-8bc5-005056917711

 

I'm attaching the pcoip_server log as well.  The drop happens in this log at about the 14:14:38 time mark.  The log truncates, and I have added the beginning section of the next log file to the attachment for reference.  Any idea what this could be?  I've seen some posts with this problem but in our case we're using a standard VM on ESXi 5.5 and no GPUs.

 

Thanks in advance! !
