It becomes trickier to handle timeout scenarios within the agent library threads. The application designer may not like asserts from OpenSAF library. Returning an error code (SA_AIS_ERR_NO_RESOURCES) could be an option, but the error code doesn't accurately reflects the situation if the timeout occurred because of a transient situation even though the user an decide to reInitialize the library at a later point of time. As you mentioned, we should perhaps just revisit this topic if such a timeout situation arises(at all)...
