Many pgfplots are included in my document, which are tikz-externalized, and run fine when the number of plots is less than 16. When I include the next pgfplot (even if it is a duplicate of the previously used ones) externalisation fails to produce the pdf (other files like md5, log are all created). While monitoring the output directory, it was noticed that the pdf file is first created, but then it gets deleted automatically. The log file of the particular plot reads like this:

......
Package pgfplots notification 'compat/show suggested version=true': document ha
s been generated with the most recent feature set (\pgfplotsset{compat=1.17}).

!  ==> Fatal error occurred, no output PDF file produced!

Note that, without externalisation everything is fine always. The tex memmory was increased to avoid capacity exceeding error. Does anybody know anything about this?

Are you by chance also using imakeidx along with tikzexternalize? I had the exact same issue, and it turns out I have to place imakeidx before tikzexternalize. i.e.

\makeindex
\usepgfplotslibrary{external}
\tikzexternalize[prefix=tikz/]
