Error description
When using the Log File Agent feature to monitor logs on a remote system (using ssh), the agent terminates in libicclib085.so. The feature to monitor remote logs is used when the *conf file includes the SshHostList keyword. Environment: Can occur across Log File Agent versions. The issue occurs when GSKit is upgraded to version 8.0.55.17 and above. The GSKit version is upgraded to 8.0.55.17 when agent shared components are upgraded to 6.30 FP7 SP6 (and above). For example, if there is an OS Agent on the same system and that agent is upgraded to 6.30 FP7 SP6, then the GSKit for all agents in that $CANDLEHOME will share the upgraded GSKit version.

Local fix
When using the remote log file monitoring of the Tivoli Log File Agent, install the agent on a system where 6.30 FP7 SP6 (or later) has not been installed.
Problem summary
There is a comability issue between the Agent Builder agent and the newer levels of GSKit (after 8.0.55.17).
Problem conclusion
This is being closed as a product limitation. The agent will need to be installed locally on the system where the logs are to be monitored.
