I upgraded the os from RHEL 7.4 to 8.4 while expanding the system.
LS-Dyna R10, 11, 12, and 13 solvers were installed in the system as single and double versions of smp and mpp, respectively, and they operated normally before the expansion.
After upgrading, when executing R10 and R11 tasks, the message *** buffer overflow detected *** occurs, and this occurs in both single and double in both smp and mpp.
The system uses the LSF scheduler, but in the case of smp, normal termination occurs when it is executed locally without going through LSF.
I got the job done locally via a simple script like this:
/gpfs/apps/lsdyna/smp/dyna971_s_R10 i='airbag_deploy.k' ncpu=18 memory=100m
I tested it with almost all kinds of R10 solvers (R10.0.0 ~ 10.2.0) of type avx512 and sse2, but the same result occurred.
Additionally, locally successful operations also resulted in buffer overflows when redirection was used to save operation results to a file.
Like, ./run_smp.sh >> local_smp_log.txt
In the case of mpp, buffer overflow occurs regardless of LSF.
The log of the failed operation is as follows.
The output (if any) follows:
*** buffer overflow detected ***: /gpfs/apps/lsdyna/smp/dyna971_s_R10 terminated
forrtl: error (76): Abort trap signal

I have already checked the following link but can't determine if it is the same problem.
Is there anything else I can try for this problem?

Please try using LS-DYNA executables built using CentOS7+ to run on RHEL 8+.
LS-DYNA R10.2 built on CentOS 7.9 are available here (https://ftp.lstc.com/beta/mpp-lsdyna/R10.2/Linux/119g/). You can also find similar builds for other versions. Please check with your ls-dyna provider for login credentials to access the ftp link.

Thanks for your advice.
I received the R10 solver mpp file built on centos 7.9 through ls-dyna provider and the test worked normally.
We plan to conduct tests on R10 smp and R11 smp and mpp as well.
