I upgraded IOS on PIX 515E from ASA image 7.2(4) to PIX image 8.0(4)16. NTP statement disappeared. I tried to add NTP statement back, but got the following error messages:
Firewall(config)# ntp server 10.3.1.3
vPif_getVpif: bad vPifNum(0xffff) from B6F781 from 560BE7
UDP: ERROR - socket <unknown> 31488 in used
ERROR: Could not open udp/65535/123 for NTP
ERROR: failed to initialize NTP process
How can I resolve this problem? Thank you in advance.
