I found a typo which seems to have caused the problem. In the \section command for the section where these subsections occurred, I closed the name of the section
<div class="">with either | or !—either way, when I changed it to } as it should be, things (so far) are compiling properly.<br class="">

I am experiencing a strange phenomenon which I am not sure I can replicate in a minimal example. Has anyone else experienced this?
<div class=""><br class="">
<div class="">I am working on a book-length project using the memoir documentclass and using a master file with \input statements for different sections, which are in separate files.</div>
<div class="">Today, I had written a brief \subsection, compiled the whole book with that, decided to change it, made changes and wrote a subsequent subsection, and compiled again.</div>
<div class="">The intial subsection showed up <i class="">twice</i>—in the proper place, and followed by (one copy of) the subsequent subsection.</div>
<div class="">I commented out all that material in the source file (there is only one copy of either subsection there) and compiled twice, hoping to shut off whatever was leading to the</div>
<div class="">loop that repeats the subsection. As desired, neither subsection appeared.</div>
<div class="">So then I uncommented the two subsections, and compiled. Again, I got two copies of (only) the initial section.</div>
<div class="">Then I copied the previously uncommented material into a new file, modified my master file to input the new file in place of the (whole chapter) file where this material had </div>
<div class="">appeared. This time the initial subsection showed up <i class="">three times</i><span style="font-style: normal;" class=""> (again followed by the succeeding section, in a single copy).</span></div>
<div class=""><span style="font-style: normal;" class="">Then I went back to my original setup (ie, took out the \input for the test file, but replaced the \input for the whole chapter.</span></div>
<div class=""><span style="font-style: normal;" class="">Now </span><i class="">that also</i><span style="font-style: normal;" class=""> compiles with three copies of the offending </span>subsection.</div>
<div class=""><br class="">
</div>
<div class="">Needless to say, I will erase the two subsections and retype everything from scratch, but I am curious about what could possibly be causing what is clearly some kind of </div>
<div class="">“do loop” that the compiler is getting from my source file.</div>
<div class=""><br class="">
</div>
<div class="">I experienced a similar issue several years ago with another book project, but did my workaround without pursuing an investigation of why it happened.</div>
