About update of CRL

Hi, all! I use FreeRADIUS-1.0.4 and OpenSSL on cygwin in Windows XP for EAP-TLS. I want to ask a question about the specification of FreeRADIUS. If CRL is updated, FreeRADIUS should be rebooted? When CRL was updated, I executed "c_rehash" command only. But the new CRL's information was not updated for FreeRADIUS. Or is there any other method? Please help me. Best regards, amemiya
