So i uninstalled libkcopat, rcu and ust. Got the latest builds of libkcompat, userspace-rcu and ust from git and installed them again in the above mentioned order. I am getting this error *root at naren-laptop:/tmp# ustctl --list-markers 23444* *ustctl[23462/23462]: Error: connect: No such file or directory (in ustcomm_connect_path() at ../libustcomm/ustcomm.c:452)* *ustcmd_send_cmd: could not connect to PID 23444* *error while trying to list markers for PID 23444* *root at naren-laptop:/tmp# * * * I guess this is same error Soumya is getting.
