ETH2 Beacon Chain validator lighthouse version2.3 was restart over 100 times

As title said, I upgrade my beacon chain validator client, lighthouse from 2.01 to 2.30, the network is ok for infura endpoints. And my lighthouse log show that the process is restart again and again from a " signal", but I have never kill the process manually.

I have contact the lighthouse developer in discord last night and we try many ways : delete the old data and rebuild, check the account for directory and fix service config ,etc... but the client is restarting again and again. So he advise me to find the AWS support for some system layer reasons. Thank you for you kindness! I am slashed by the ETH Council mechanisms because of I am down, for a loss about 20 -50 US dollars per day... So pls help me to stop the leak..

Thank you !
