Recently I have faced the following problem: after compilation in LaTeX, I am getting following error: !Output loop-----100 consecutive dead cycles. \break -> penalty -\@m

Hence the compilation is becoming incomplete.

I am providing here my file.

The problem is, after preparing 21 questions like this, when I am preparing 23rd question, the error message is appearing. What to do?

Just see what happens if you remove % in Q22.

    My guess would be that something with question 23 is strange. I cannot even compile your example because \question is undefined. On the other hand, there are packages for that kind of stuff. – Johannes_B May 20 '16 at 6:30

    Your MWE is working (for me) -- even with 23 questions... maybe it is within the 23rd question (i.e. the code in it) that there is a typo that leads to this error... ( A tip: You can use backticks ` to mark your inline code ) – ebosi May 20 '16 at 6:36

    what about actually posting it in your question, since it is what you're asking? (for what concern privacy, just replace your real content by dummy one, e.g. \question\label{Question 13} Let $1+1=0$. Blablah. \choice $1$ \\ \choice $2$ \\ \choice $3$ \\ \correctchoice $4$) – ebosi May 20 '16 at 7:30

    all the Underfull \hbox (badness 10000) in paragraph at lines 159--160 are due to misuse of \\ which should never be used at the end of a paragraph (otherwise it always produces bad spacing and the underfull box warning) – David Carlisle May 20 '16 at 8:01

    Make sure that the example really shows the error: Copy it in a new document and compile it. If it shows the error put the document and the log-file in a zip-file and upload it somewhere on the net. If it doesn't show the error make a true example that does. – Ulrike Fischer May 20 '16 at 8:34
