[Gate-users] Attaching process problem

[Kiara Govia]

Hello everyone,

I am currently trying to use the CPET that I found in the user manual,
however I keep getting this error:

*** Break *** segmentation violation
Attaching to program: /proc/6595/exe, process 6595
Could not attach to process.  If your uid matches the uid of the target
process, check the setting of /proc/sys/kernel/yama/ptrace_scope, or try
again as the root user.  For more details, see /etc/sysctl.d/10-ptrace.conf
ptrace: Operation not permitted.

Below is what I use to try to get it to run. I checked if there's any
overlapping using /geometry/test/recursive_test and no errors came up:

Any help would be greatly appreciated.
