Known Causes

4 known causes
⚠️
Network Connectivity Issues
Network interruptions between the Oracle server and the remote agent can lead to a lost connection. This might involve packet loss, firewall restrictions, or routing problems.
⚠️
Remote Agent Crash
The heterogeneous services agent itself might have crashed or terminated unexpectedly. This can be due to software bugs, resource exhaustion, or external interference.
⚠️
Non-Oracle System Failure
The target non-Oracle system (e.g., a different database) might be unavailable or experiencing issues. This can cause the agent to fail and break the RPC connection.
⚠️
Resource Limits Exceeded
The agent server may be facing resource constraints like memory or CPU utilization, causing the connection to drop.
