end=10000
 
i=0
 
connection= mariadb.connect(user="georg")
 
last_used_mem= resource.getrusage(resource.RUSAGE_SELF).ru_maxrss
 
 
 
while i < end:
 
     cursor=connection.cursor()
 
     cursor.close()
 
     diff_mem= resource.getrusage(resource.RUSAGE_SELF).ru_maxrss - last_used_mem
 
     if diff_mem > 0:
 
        print("leak: %s" % diff_mem)
 
        last_used_mem+= diff_mem
