forrtl: severe (174): SIGSEGV, segmentation fault occurred

#1 Unread post by agpc »

Dear everyone,
I'm a beginner of COAWST model. Currently, I'm running COAWST (WRF+ROMS+SWAN) with nonesting option.
In this case, I used WRF with 2 domains, ROMS and SWAN with 1 domain.
My error is displayed below:

Code: Select all

i looked at your ocean.in and there are a lot of TABS in there. if dont know if this is exactly the problem, but i remember other people had trouble when there are tabs in the ocean.in.
You need to clean up that file. there are editing tools to do this. then give it another try.
for coawst related issues, you can post those on our github site:

Hi John,
Thank you for your suggestion, however when I deleted all of TAB, the error still occurred.
Can you kindly give me any suggestions?
I also post my issue on your github site.
Many thanks!

When you get a seg fault, you can recompile with USE_DEBUG to get line numbers in the output. You then need to look at the relevant lines in *your* .f90 files.

Hi Kate,
I'm sorry if my question is quite stupid. I mean your suggestion is that I recompile model with USE_DEBUG option in coawst.bash file, isn't it? I'm a beginner, so I know not much about this model.
Many thanks!

1. Yes, Kate is suggesting you edit the coawst.bash (or roms.bash) and set
USE_DEBUG=on
2. can you post your cleaned ocean.in
3. the error was
coawstM 000000000092471A edit_file_struct_ 212 edit_multifile.f90
coawstM 000000000090A307 read_phypar_ 2198 read_phypar.f90
so if you edit Build/read_phypar.f90, what is happening near lines 2198?

Hi all,
1. I had a problem when recompiling COAWST model with USE_DEBUG option but it failded.
The error is that:

Code: Select all

fort: warning #10182: disabling optimization; runtime debug checks enabled
swanpre1.f90(4637): error #7938: Character length argument mismatch.   ['(I6)']
         CHARS(1) = NUMSTR(ISTAT,RNAN,'(I6)')                             40.41
--------------------------------------^
compilation aborted for swanpre1.f90 (code 1)
make: *** [Build/swanpre1.o] Error 1
[cloud@igplogin COAWST9]$ exit
I also attached my build.log file in this email.
2. Regarding to my ocean.in file, it is also included in the below of my post.
Please help me to fix it.
Thank again,

ok. SWAN has some issues with the arrays, and depending on the debug flags, it will stop compiling. swan is not the problem, so lets not go down this road.
the problem you were having is with roms. it stopped when it tried to close a file.
how about you setup the application to only use roms. then compile it in debug mode, and run that.
sorry for all this round about, but sometimes this is what it takes to figure it out.

Hi everyone,
Thank you for your help. My problem is definded in the differences of the Theta_S, Theta_B, minimum depth of ROMS grid and ROMS namelist file. After I recreate all of the input and namelist file, unfortunately it reported that:
Found Error: 01 Line: 351 Source: ROMS/Nonlinear/main3d.F
Found Error: 01 Line: 332 Source: ROMS/Drivers/nl_ocean.h
When I showed the line in these files, it was:
IF (FoundError(exit_flag, NoError, __LINE__, &
& __FILE__)) RETURN
Can anyone kindly help me to solve this issue? Thanks a lot!!

you need to look more closely at the whole output. The coupled simulation ran for 0.5 hours:

Looks like the data of SWAN to ROMS is rather large. something is going on in SWAN. Some next steps would be:
- look at the roms his file and see what the fields look like.
-rerun and output more frequently (every 5 min or so, just until you figure out what is wrong).
-run just roms
-run just roms + swan
-run roms + swan + wrf
you will need to dig in and see what is going on.
