invalid context root:sysadm_r:initrc_t?

[dragoran]

hello I found this errors in dmesg on a FC4 system using 
selinux-policy-targeted-1.27.1-2.16:
audit(1137825680.353:2): security_compute_sid:  invalid context 
root:sysadm_r:initrc_t for scontext=root:sysadm_r:unconfined_t 
tcontext=system_u:object_r:initrc_exec_t tclass=process
audit(1137825680.617:3): security_compute_sid:  invalid context 
root:sysadm_r:initrc_t for scontext=root:sysadm_r:unconfined_t 
tcontext=system_u:object_r:initrc_exec_t tclass=process
what are this errors? what does invalid context means?
