    Hello,

    Can you confirm if you have sufficient memory allocated with the following command.

    sudo sh -c "echo 20 > /sys/kernel/mm/hugepages/hugepages-\ 2048kB/nr_hugepages"

    Also, if you are using multiple PAC cards, you need to allocate more memory.

    thanks

Folks,

What was the solution to this issue? I am having the same problem. From this ticket, it is not clear how the issue got resolved?

Ofcourse, I am unable to run in sudo mode.

Dear User,

this server does not allow you to run "sudo".

If you need to install a dependency, please put it in your home directory.

* For autotools, you can do it with "./configure --prefix=~/my-path"

* For Python packages, use "pip install <package_name> --user" or create a Conda environment.
