Service account getting locked unexpectedly

Hi Team,

We are facing strange with one of our BO Dev system.

SIA is unexpectedly stopping few times with following error.

The BOEXI40SIABIXUSCORE2AUSCORED1N1 service was unable to log on as service account with the currently configured password due to the following error:

The referenced account is currently locked out and may not be logged on to.

and

Server Intelligence Agent: server <node>.ConnectionServer stopped with exit code = 0 (0x0) getting these type of errors for all server in Dev system

SIA was failed with same error 3 days back and today again.

This type of issue is not happening with other system, both environments service accounts are having similar type access and no difference.

Appreciate your response on this.

Thanks,

Narendar
