Can't connect IPSec if other IPSec connected

[syafii404]

I have 2 IPSec configuration connect to diffrent host.
-IPSec A using algo (AES_CBC (256),HMAC_SHA2_256_128,PRF_HMAC_SHA2_256,MODP_2048)
-IPSec B using algo (AES_CBC (128),HMAC_SHA1_96,PRF_HMAC_SHA1,MODP_1024)

When IPSec A already ESTABLISHED, IPSec B can connect and ESTABLISHED too, so there are 2 Established IPSec connection.

The problem is where IPSec B connected first and ESTABLISHED, IPSec A can't connect and stuck on CONNECTING. This condition also occurs if the connection IPSec A Reauth connection (Reauth after 21h established) its stuck on CONNECTING. So i have to disable both IPSec and enable&connect IPSec A first again. Reauth on IPSec B never get trouble.

Can u help me to solve my problem, please?
Thank you.
