Last updated on FEBRUARY 27, 2019

Applies to:

Oracle Exadata Storage Server Software - Version to [Release 11.2]
Information in this document applies to any platform.


Oracle Exadata, with exadata software version or earlier.

All database and ASM instances report the following message in their alert logs:
"connect: ossnet: connection failed to server <cell IP address>, result=5 (login: sosstcpreadtry failed)"

The message gets repeated many times as the cell server cannot accept new connections.

Database instances may become unresponsive and have to be shutdown aborted/restarted to recover.
