The indicated coupling facility has experienced the indicated number of Interface Control Checks (IFCCs) on the indicated coupling facility CHPID over the indicated period of time preceding the issuance of this message. Note that this count only reflects IFCCs on requests from this system, not all systems in the sysplex.
The system continues operation. Normally, Interface Control Checks are fully recoverable by the system. If the IFCC resulted from a more serious failure condition (for example, the failure of a CF or of a coupling facility CHPID), other messages will be issued to describe those conditions.
Notify the system programmer.
If the indicated coupling facility CHPID, or the coupling facility as a whole, is experiencing small numbers of IFCCs on a sporadic basis, generally no action is needed. Such sporadic IFCCs may be caused by events such as a temporary CF link problem, a workload spike or temporary delay in the CFF image, a system joining or leaving the sysplex, structure rebuild or other structure recovery actions, and the like. However, larger numbers of IFCCs occurring on a frequent or continual basis may indicate a hardware problem that requires further analysis or action. More detailed information on each IFCC is recorded in LOGREC for analysis, and hardware logging may also be taking place for these errors. Frequent or continual IFCCs may indicate that the CF is running with degraded performance due to a hardware or microcode problem. Consult IBM® service personnel if the IFCCs cannot be understood in terms of normal events taking place in the configuration.
