# Troubleshooting ## libadaptyst.so not found After installing Adaptyst, you may get an error like the one below when trying to run the tool on Linux: ``` adaptyst: error while loading shared libraries: libadaptyst.so: cannot open shared object file: No such file or directory ``` If this happens, please add ```/lib``` (it's ```/usr/local/lib``` by default) to ```/etc/ld.so.conf``` and run ```ldconfig``` afterwards. Alternatively, run Adaptyst with ```/lib``` appended to the ```LD_LIBRARY_PATH``` environment variable. ## Adaptyst keeps running for long time after my workflow finishes executing in all entities Depending on your system graph and workflow, the amount of information to be processed by modules may be too large for Adaptyst to finish at about the same time when the workflow completes. If you have multiple CPUs/cores, please see if setting the ```processing_threads``` entity option to a number higher than 1 in your system definition file helps (linuxperf is one of the modules using that option).
