# service qpidd start Starting Qpid AMQP daemon: /etc/init.d/qpidd: Usage: daemon [+/-nicelevel] {program}
Sorry, this is happening on a RHEL4 system.
The calls to 'daemon' and 'killproc' helpers used in the init script contained rhel5-specific options. I removed them and it appears to work correctly.
Verified that this is fixed in qpidc-0.2.667253
