WRF writing only a frame per wrfout file after one day of restart run

Hello all,
I'm using WRF4.7.1 to run a 1-year simulation (2016-01-01 to 2016-12-31) which encounters segmentation fault at 2016-05-23_08:00:00, because I set write restart files per 5-day, so the latest restart file is wrfrst_d01_2016-05-20_00:00:00. Therefore, I changed the namelist to do a restart run, set start time as d01_2016-05-20_00:00:00, it can normally running. What I want is to write history file per 6-h and 4 frames per file, so wrfout files are generated on a daily basis. But when I check the new wrfout files, I find that only wrfout_d01_2016-05-20_00:00:00 has 4 timestamps, all wrfout files starting from 2016-05-21 contain only a single timestamp at 00:00.
The namelist snippet of restart as follows:
Code:
start_year                          = 2016,
start_month                         = 05,
start_day                           = 20,
start_hour                          = 00,
end_year                            = 2016,
end_month                           = 12,
end_day                             = 31,
end_hour                            = 23,
interval_seconds                    = 21600
input_from_file                     = .true.,
history_interval                    = 360,
frames_per_outfile                  = 4,
restart                             = .true.,
restart_interval                    = 7200,
override_restart_timers             = .true.,
write_hist_at_0h_rst                = .true.,
Also, I checked rsl* files and found infos like "Timing for Writing wrfout_d01_2016-05-21_06:00:00 for domain 1: 0.38801 elapsed seconds", but the wrfout file contains no timestamps other than 00:00.

Hope you can give me some help, many thanks! (This forum cannot upload files now, I will attatch my namelist.input and rsl* files as soon as possible after the website is fixed.)

Hi Yuting,
Are you able to attach your full namelist now? If not, try to use a different browser to see if that helps. You can also paste the full namelist here so I can see if there are any other settings causing this issue.

Please also issue the following and if you're able, attach the ls.txt file here:
Code:
ls -ls wrfout* >& ls.txt

and then issue the following, using the full name of the 2016-05-21 wrfout file, then attach the times.txt file, if you're able:
Code:
 ncdump -v Times wrfout-file-name >& times.txt
