Python arcpy 更新游标循环中断

Question

制作此脚本是为了清除 table 行，而在另一个 table 中没有对应的行（必须通过 arcpy 制作，因为 table 是一项功能 class 启用存档，来自 ESRI）。我正在生产中测试这个脚本，所以，我只是使用一个计数器，而不是实际擦除行。但是，当计数器 'excluidos' 的值约为 310000 时，脚本就会停止。 arcpy 更新游标有内存限制吗？（通常我会收到一些 python 内存错误消息，但这里不是这种情况）或者这里有一些我遗漏的逻辑问题？

我认为限制是在 arcpy 上，所以我应该在 GIS Stack Exchange 上提出问题。无论如何，我 'resolved' 这个问题有一个更慢的解决方案，为每个排除启动和停止版本：

print str(time.strftime('%x %X'))
print 'Iniciando busca de registros no workspace: ' + fc2

listAIA = []
listVist = []
listIg = []
adicionados = 0
ignorados = 0

with da.SearchCursor(fc2, (campos2)) as sc:
    for row in sc:
        if row[0] <> None:
            listVist.append(row[0])

with da.SearchCursor(fc, (campos)) as sc1:
    for row in sc1:
        verifExcec = False
        if row[0] <> None:
            for vist in listVist:
                if int(row[0]) == vist:
                    verifExcec = True
            if verifExcec:
                ignorados += 1
                listIg.append(row[0])
                continue
            else:
                listAIA.append(row[0])
                adicionados += 1
        else:
            ignorados += 1
            listIg.append(row[0])

print str(time.strftime('%x %X'))
print 'Iniciando exclusao de registros no workspace: ' + fc

col_1 = 'NIS'
excluidos = 0
multiplo = 100000

for reg in listAIA:  
    expressao = '"' + col_1 + '" = ' + str(reg)
    try:
        edit = da.Editor(workspace)
        edit.startEditing(False, False) #undo/multiuser
        edit.startOperation()
    except Exception as e:
        print e
        sys.exit(0)

    try:
        with da.UpdateCursor(fc, (campos), expressao) as cursorExc:
            for row in cursorExc:
                #cursorExc.deleteRow()
                excluidos += 1
                print u"{0} - {1} ".format(time.strftime('%x %X'), excluidos) + u" registros excluídos até o momento."

    except Exception as e:
        print e   

    try:          
        # Stop the edit operation.
        edit.stopOperation()    
        # Stop the edit session and save the changes
        edit.stopEditing(True)
    except Exception as e:
        print e

    if (excluidos % multiplo == 0):
        print u"{0} - {1} ".format(time.strftime('%x %X'), excluidos) + u" registros excluídos até o momento."
