Solution #00005729

 

Scope:

This solution applies to the Barracuda NG Firewall firmware versions 4.2.x, 5.0.x, 5.2.x.

Symptoms:
Sometimes, the system time will become out of sync on legacy M3 boxes. When you sync the time manually, and then query the NTP server multiple times, you can see the time falling out of sync:
(The queries below are about 5 seconds apart)

# ntpdate -q 10.0.10.10
server 10.0.10.10, stratum 3, offset 281791.965537, delay 0.02559
2 May 08:55:13 ntpdate[20785]: step time server 10.0.10.10 offset 281791.965537 sec

# ntpdate -q 10.0.10.10
server 10.0.10.10, stratum 3, offset 281792.009489, delay 0.02559
2 May 08:55:15 ntpdate[20818]: step time server 10.0.10.10 offset 281792.009489 sec

ntpdate -q 10.0.10.10
server 10.0.10.10, stratum 3, offset 281792.078668, delay 0.02559
2 May 08:55:19 ntpdate[20842]: step time server 10.0.10.10 offset 281792.078668

Answer:
Adding the boot parameter "tsc=reliable" solves the issue, keeping both system and hardware clock in sync.

The Parameter should be inserted in the Boot-loader options, under Box > Advanced Configuration > Bootloader > Global Append Options.
