I am trying to compile my manuscript. I am using a large bibtex database that contains conference papers, in addition to my custom bib file.Also I am using the CCS template, as follows:
\bibliographystyle{ACM-Reference-Format}
\bibliography{mybibliography,abbrev3,crypto}
But when I compile my tex, I am getting the following errors, and the reference list does not show up:
This is BibTeX, Version 0.99d (TeX Live 2017/Debian)
The top-level auxiliary file: main.aux
The style file: ACM-Reference-Format.bst
A level-1 auxiliary file: appendix.aux
Database file #1: mybibliography.bib
Database file #2: abbrev3.bib
Database file #3: crypto.bib
Sorry---you've exceeded BibTeX's hash size 100000
Aborted at line 291526 of file crypto.bib
(That was a fatal error)
Process exited with error(s)
However, if I break the bib files into 3 separate lines, it compiles (with some warnings) but I am getting my references displayed 3 times...
\bibliography{mybibliography}
\bibliography{abbrev3}
\bibliography{crypto}
Is there any solution for that? I have tried looking on how to increase the Bibtex hash size but couldn't find anything...
