VDX 2730 crashing during normal operation with a TS failed to refresh error

During normal operation, the VDX 2730 may undergo an unexpected reload, with the RASLOG showing the following error:
 

2019/04/17-13:54:56, [HASM-1201], 248643, FFDC, WARNING, chassis, ts:2375 failed to refresh (7197637:7194254).

 

The reload is caused by the time service daemon (TSd) crashing due to a watchdog timeout. When NOS contacts the TSd, NOS will wait for a response, however when this defect is encountered TSd is not able to return a response and NOS ends up in a locked state, eventually crashing. The crash only occurs when NTP server config is present on the device.

Remove all NTP config and revert back to local time.

The defect ID is 000555411 and is fixed in NOS4. Unfortunately the VDX 2730 can only run up to NOS 3.0.0_dcb.
