resource request is rejected;
3) make error message string generated in resource manager process only for
all resource manager RPCs;
4) change NVSEG_* limits semantic meanings to latest version;
5) minimum vseg number for one resource request is changed to queue vseg
num / active_statements, but the request having only a few vseg required is not
