Summary
This error message appears when doing a direct upgrade from DSA 7.0 to version 8.0:
“Agent Software Upgrade Failed (Send software failed)”
System Events displays the following errors:
- Agent Software Upgrade Failed
- Unable to send the software upgrade program to the Agent due to the following error: SocketException: Connection reset by peer: socket write error.
Details
This issue happens because of a limitation in Deep Security Agent 7.0 wherein the installer size should not exceed 7MB (compressed size). The DSA 8.0 installer, on the other hand, is about 22MB. The original purpose of this limitation is to verify the installer size.
This limitation was increased to 200MB in DSA 7.5.
As a workaround, upgrade DSA 7.0 to version 7.5 first, then upgrade to DSA 8.0.
