rsync error: errors selecting input/output files, dirs (code 3) at main.c(631) [Receiver=3.1.1]
Error: Got non-zero exitcode 3 from __sync_exec().
Error: Got error-report from exitcode_process().
Exitcode is 3, strerror(3) returns "No such process". However strerror() is not ensures compliance between exitcode and error description for every utility. So, e.g if you're using rsync, you should look for the error description into rsync's manpage ("man 1 rsync"). Also some advices about diagnostics can be found in clsync's manpage ("man 1 clsync", see DIAGNOSTICS)
Warning: __sync_exec_thread(): Bad exitcode 3 (errcode 3). Give up.

Error: Got error from thread #0: errcode 3. (4: Interrupted system call)
Error: got error while sync_idle(). (4: Interrupted system call)

Looks like capabilities code is responsible: with --disable-capabilities clsync works fine.
