How can i solve this problem

$19114$:CCREAT

A runtime error was detected at time $1965\mathrm{.}633$ at the following block:

$*144$$ CREATE,$1,$MinutesToBaseTime$(0\mathrm{.}0),$Customer:

MinutesToBaseTime$($UNIF$(5,20))$:

NEXT$(45$$$)$;

Maximum of $150$ entities exceeded.

Possible causes:

$-$ A logic problem in your model is creating too many entities or not

disposing them. The run controller may be helpful in finding the problem.

$-$ You are in demo mode and have exceeded the entity limit$.$ The commercial

version is required to run large models.

$-$ You have set an entity limit on the DISCRETE element that is too small.

Remove the limit or set it to a larger number.

$-$ You have exceeded the standard array s

pace for models. Use the Array Sizes

page in the Run$/$Setup dialog to increase the RSET space allocated and

recheck your model.
