Dear application developers,
the mentioned applications appear to attempt to create files outside of the BOINC data directory (probably in /var/tmp and /usr/tmp). On many recent Linux distributions, boinc-client is started by default such that writing outside the BOINC data directory is not permitted. Therefore all tasks immediately fail with the mentioned error on such hosts. You should fix the application to create files only within the working directory. Users may not be able or willing to change the boinc-client service startup to a less secure mode.

thanks for the information, we will take it into account in future versions
