When I try and sign the bitstream of this version of my aocx, it just stops running partway through. There was very few changes made to the kernel before compiling, so I'm not sure what's wrong

kmellen@npsw6:~/pannotia/graph_app/prk$ $AOCL_BOARD_PACKAGE_ROOT/linux64/libexec/sign_aocx.sh -H openssl_manager -i kernel_single_unsigned2.aocx -r NULL -k NULL -o kernel_single_fpga.aocx
The script assumes the PACsign and Intel Acceleration Stack environment is setup. If not run the command : <stack_installation_path>/init_env.sh
hsm_manager=openssl_manager
aocx filename/path=kernel_single_unsigned2.aocx
root_public_key=NULL
csk_public_key=NULL
output filename/path=kernel_single_fpga.aocx
null=1
openssl hsm_manager_options=openssl_manager
input path =.
input filename =kernel_single_unsigned2.aocx
output path =.
output filename =kernel_single_fpga.aocx
Extracted the filename as kernel_single_fpga

This is what it normally looks like when I try to sign it.

1. Extracted the bin from the aocx
2. Extracted the gzip compressed GBS file from the .bin
gzip: temp_kernel_single_fpga.gbs already exists; do you wish to overwrite (y or n)? y
3. Uncompressed .gz it to get the GBS file
Initiating PACSign tool to sign the GBS. This process will take a couple of minutes...
Creating unsigned aocx file by signing a NULL key
No root key specified.  Generate unsigned bitstream? Y = yes, N = no: y
No CSK specified.  Generate unsigned bitstream? Y = yes, N = no: y
4. Signed the GBS
gzip: signed_kernel_single_fpga.gbs.gz already exists; do you wish to overwrite (y or n)? y
5. Compressed the gbs file
6. Added the signed gzip file to fpga.bin
7. Added the fpga.bin file back into aocx file
The signed file kernel_single_fpga.aocx has been generated. Use the command aocl program <device_name> <filename>.aocx to program it on the FPGA card
