Error description
The SNMP Agent terminates with message EZZ6247I after five EWOULDBLOCK errors occurred on accept processing for TCP connections from subagents. The Agent externalizes the following EZZ6242I message: . EZZ6242I accept function failed for a DPI inet socket; EDC8102I Operation would block. . The EZZ6242I message for the EWOULDBLOCK error indicates that the connection no longer existed when the Agent attempted to accept the subagent connection. This type of error should not cause the Agent to terminate.
