Restart an Explicit simulation?

[RGX124]

Hello,
An explicit simulation crashed after an electricity shutdown. I did a restart for explicit with the following command:
abaqus job=toto recover

toto being the same input file.
Unfortunately, the simulation stops after 2 hours with the following error message:

Abaqus JOB v40_a90_d600_r3_t150_titanium_100Cr6_f8_C3D8R-billesquad2_cf400-exp
Abaqus Version 6.7-1

Abaqus Error: The executable /software/ABAQUS/6.7-1/exec/explicit.exe
aborted with system error "Abnormal termination signal" (signal 6).
Please check the .dat, .msg, and .sta files for error messages if the files
exist. If there are no error messages and you cannot resolve the problem,
please run the command "abaqus job=support information=support" to report and
save your system information. Use the same command to run Abaqus that you
used when the problem occurred. Please contact your local Abaqus support
office and send them the input file, the file support.log which you just
created, the executable name, and the error code.
Abaqus/Analysis exited with errors


Do you have any clue of how else can I restart the explicit simulation?

Thanks a lot for your advices.
