You can increase the maximal number of iterations. See 'options' in the doc or help for svmtrain.

thank you for answer i increase MaxItr to inf, but did not fix the error.

Then do one or all of:

lower the box constraint
increase tolkkt
specify a positive value for kktviolationlevel
try a different kernel function
