... I'm running Solaris 2.4 X86. Compiled hylafax with gcc/g++ 2.7.0. When I first run faxq it does not max out the CPU until I send the first fax. From then on it uses 99% of the CPU.
CONFIG_OPENFIFO="O_RDWR"in config.site, removing port.h, re-configuring and re-building the faxserver.
BTW: There also other systems having this bug; e.g.: Linux kernels post 1.3.78
