Thanks for including the verbose option @yarikoptic. The relevant output where the tests fails is

XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server ":20"
2:       after 7415 requests (7398 known processed) with 0 events remaining.

I came across a relevant message (https://afni.nimh.nih.gov/afni/community/board/read.php?1,146837,146837):

a recently changed AFNI default is to auto-detach from terminal, which is probably more convenient for most users. There is just one small limitation if you use drive AFNI in a virtual X11 server environment (Xvfb) executed e.g. like this: 
xvfb-run -a --server-args='-screen 0 1280x1024x24' afni -com 'SAVE_JPEG A.axialimage sss.jpg' -com 'QUIT' 
> more details [afni.nimh.nih.gov] 

If you use a fresh AFNI version, you potentially get the following error: 
XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":100" 
after 16152 requests (16109 known processed) with 0 events remaining. 

My bug fix was rather simple and easy to share - just add the flag '-no_detach' to the afni drive command and all works as in previous versions. 
xvfb-run -a --server-args='-screen 0 1280x1024x24' afni -no_detach -com 'SAVE_JPEG A.axialimage sss.jpg' -com 'QUIT' 

will try and see if using the "no_detach" option when running the tests resolves the issue.

[nno]

It seems that the no_detach option is afni specific, whereas the do.examples script contains many calls to DriveSuma (which /may/ cause the fatal IO error 11). So I'm not sure if the no_detach option can actually be used; or even whether it could fix the problem running the do.examples script on travis.
