We are having libxm2 version 2.6.16-12.9 and perl-5.8.5-57.We are getting following errors intermittently when calling a perl script through a C program.

We are calling the perl script multiple times with the same parameter but sometimes we see this error. As a workaround for this problem, many of the links on web suggested altering  the order of modules SAX and ParserFactorey names in ParaserDetails.ini. We changed it and moved SAX before SAX::Parser, but still get an error although a different one -
