Random suggestion: don't hook dlopen? For new versions of VGL that means use -nodl, for some old versions it means upgrade to a newer version. :) If the trace line is completely written it suggests that the hang is outside VGL's code, but a debugger might give a slightly better perspective (backtrace on hang, at least). Building a debug VGL isn't hard, roughly: - unpack libjpeg-turbo tarball - ./configure --with-jpeg8 - make - unpack vgl tarball - # if you didn't install, edit Makerules to know where your libturbojpeg.so is - make DEBUG=yes -Nathan ------------------------------------------------------------------------------ Forrester Wave Report - Recovery time is now measured in hours and minutes not days.
