[Tugindia] No room for a new \write - backref package error

[Jay]

Hello Group,

I want to create a pdf file for conference proceedings with links by
using hyperref.sty. The proceedings contain chapters by different
authors and each chapter has its on bibliography.

Processing the file with the hyperref option pagebackref=true causes
the well known

[215] (main.brf)
! No room for a new \write .
\ch at ck ...\else \errmessage {No room for a new #3}
                                                  \fi
l.754 \begin{thebibliography}
                             {99.}
?

error. Is there any solution to this problem. I checked the same on
net but I haven't got any solution for the same. Kindly suggest.

My Main TeX file structure as below:

\documentclass{book}

\usepackage{makeidx}
\usepackage{graphicx}
\usepackage[bottom]{footmisc}
\usepackage{multicol}
\usepackage[breaklinks,pagebackref=true,dvips]{hyperref}
\def\backrefsep{, }%
\def\backreftwosep{, }%
\def\backreflastsep{, }%
\renewcommand*{\backref}[1]{\ignorespaces}
\renewcommand*{\backrefalt}[4]{             %............. Back
reference format
\ifcase #1 %
     %(Not cited.)%
\or%
   \leavevmode\nobreak{\hbox to 0pt{#2}}%
\else%
   \leavevmode\nobreak{\hbox to 0pt{#2}}%
\fi} %

\makeindex

\begin{document}

\include{art1}
\include{art2}
\include{art3}
\include{art4}
\include{art5}

\printindex

\end{document}
