javax.net.ssl.SSLException: Inbound closed before receiving peer's close_notify: possible truncation

Hi I am getting this issue and sgadmin.sh hangs when running it ?

You can ignore the "javax.net.ssl.SSLException: Inbound closed before receiving peer's close_notify: possible truncation attack?", thats not the cause of your problem.
(Its a harmless exception and its logged on DEBUG level)
To figure out why sgadmin hangs we need a few more details:

- Search Guard SSL and Search Guard version
- Cluster size (how many nodes)
- Operating system vendor and version
- Do you run elasticsearch within a cloud environment (aws, ...)
- Java version and vendor
- Complete elasticsearch logfiles (every node) on DEBUG level (from elasticsearch start until sgadmin is finished/hangs)
- Complete output of sgadmin
