[Python] Сonnection timeout for function does not seem to work in Python script

for some reason the connection timeout does not seem to work when connecting to a Firebird database. For example, if an incorrect IP address is specified, the script hangs and waits for a long time.

#!/usr/bin/python3

import fdb
import timeout


HOST = '172.19.76.10'
DBS = [
'test_db_1102',
'test_db_10025',
'test_catalog',
]
USER = 'SYSDBA'
PASSWORD = '123'


def check_db(DB):
print(DB)
con = fdb.connect(host = HOST, database = DB, user = USER, password = PASSWORD )
cur = con.cursor()
cur.execute('select first(1) * from objects')
print(cur.fetchall())


for DB in DBS:
timeout.timeout_check(check_db(DB),5)



list timeout.py:

#!/usr/bin/python3


import multiprocessing
import time


def timeout_check(func, func_timeout):
p = multiprocessing.Process(target=func)
p.start()
p.join(func_timeout)

if p.is_alive():
print ("running... let's kill it...")
p.terminate()
p.join()




I tried using other timeout functions based on the signal library, but that also does not work
