用arcgis里的erase工具遇到的问题，恳请赐教

<P>我在用erase工具是，提示以下错误：</P>
<P>Sorting...<BR> Intersecting...<BR> Assembling polygons...<BR>Statistics array limit (POLSCN)<BR>ISP channel# 1 was not properly closed (INFEND)<BR>Bailing out of BUILD<BR><BR>ODE sub-process failed</P>
<P>这是怎么回事呀？该怎么解决，也用arc命令做过，一样的问题！</P>
<P>哪位大侠知道，恳请告知，不胜感激！！</P>
