After doing a yum update on a RHEL5 box to take it to update 2, Amavis
fails to start if it is not in debug mode. The difference appears to be
that in debug mode, Amavis never forks. When running outside of debug
mode, Amavis fails to fork a child, so thus refuses to start:

or directory)

(Inappropriate ioctl for device)
lseek(5, 0, SEEK_CUR) = 0
fstat(5, {st_mode=S_IFCHR|0666, st_rdev=makedev(1, 3), ...}) = 0

Since debug mode works, it's hard to gather data on why children won't
fork. Any thoughts?
Thanks,
