Discussion:
A failed host ip can remain in the dynamodb?

Hello,

I had this issue several times and am not sure how to fix it.
Sometimes on a failed transactor, it seems that the machines that try to
connect to the db are trying to connect to a transactor ip that does not
exist.
If I check the aws.properties of my transactor it states: host=10.0.11.186
Yet I see messages in the peers with errors: Error communicating with HOST
10.0.10.236 on PORT 4334
Is it correct that that ip should be the one from my aws.properties host?
How is this possible, since there is only one transactor running, it should
be impossible to receive an other IP which are stored in dynamodb if a
transactor registers right? So what could be the cause that the 'active'
transactor registered in dynamodb is actually a dead transactor.

PS: I waited quite some time by now (weekend), in the meantime the peers
have restarted several times and I restarted the transactor 2-3 times as
well. The ip they try to connect on still remains '10.0.10.236'. What could
be wrong?

Kind Regards
Brecht
