I'll look into this some more. The problem cited is the third one in a homework folder. When printing all problems in the folder, I get a pdf containing the first two problems, and nothing else. Your tips should help me troubleshoot exactly where the issue is---it could be in the second problem, perhaps.
Anyway, thanks for the tips and I'll see what I find.

I switched my web session to a number of other servers in the network currently running 2.11.1 and found that a non-blank PDF was also generated on servers in other domains where the Linux distro was CentOS 5 or 7, or Ubuntu 12 or 14. However, a blank PDF was the result on some (but not all) servers running CentOS 6. > ... Now, I just get a link to the pdf file and nothing else. Is > there a way to find the log and TeX files with 2.11.1? There has not been a change in the display of links to the .log and .tex files in 2.11.1 as compared with earlier LON-CAPA versions. Those links are displayed to "advanced users" (e.g., Course Coordinators, Authors/Co-authors etc.) when an "Emergency stop" is found in the log file. If printout generation is successful and the various stages of the process are completed (i.e., calls to latex, dvips, ps2pdf13 complete etc.) then the corresponding files with extensions .log, .tex, .ps and .pdf will remain in the prtspool directory, until the nightly clean-up by cleanup_file_caches.pl. You can access the .log, .tex etc. files by replacing the .pdf extension, with the extension for the desired file in your browser's address box. If you right click (or ctrl-click for Mac) on the link: "Your PDF file" in the text: <Name> - Your PDF file is ready for download, in the final printout generation screen then you can copy the link location, which will be of the form: http://loncapa.tcc.fl.edu/prtspool/<user>_<domain>_<identifier>.pdf Comparing sizes for the various files generated when printing /res/msu/kortemey/physicsprecourse/geometry/arclength.problem (imported into a course) in the same course for the same user on msua4 (i.e., s4.lite.msu.edu) versus tccfll1 (i.e., loncapa.tcc.fl.edu) I find: 2412 msua4.dvi 26010 msua4.log 30978 msua4.pdf 999358 msua4.ps 3740 msua4.tex 1001384 msua4temporar.ps 2408 tccfll1.dvi 26010 tccfll1.log 9360 tccfll1.pdf 1003401 tccfll1.ps 3740 tccfll1.tex 1005427 tccfll1temporar.ps A diff of tccfll1.tex and msua4.tex reports no differences. However the .dvi files are different, and in addition the .ps file generated on loncapa.tcc.fl.edu cannot be displayed with a postscript viewer. The issue would seem to be in the generation of the .dvi file within cgi-bin/printout.pl from the command: "latex filename.tex 1>/dev/null 2>/dev/null" where filename is the name of the .tex file. Note: loncapa.tcc.fl.edu and s4.lite.msu.edu have the same Linux distro, and architecture.
