Consider the following scenario:
Event ID: 102:
Source: HIS Application Integration
HISETBG0001 Application Integrator has intercepted an exception in method MethodName. Following is the exception description: HISMSNA0015 The SNATransport encountered an error calling internal method CMALLC when processing method MethodName, LUName APPC LU Name, Error = 1."
This issue occurs because TI does not call the TP_ENDED verb at the end of an APPC transaction when the host application deallocates the APPC conversation. The internal Transaction Program (TP) control block for the APPC conversation is not released when the TP_ENDED verb is not called. Over time, the maximum number of TP control blocks is reached, which prevents additional APPC transactions from starting. Therefore, this issue occurs when the host application tries to allocate a new APPC conversation when the maximum number of TP control blocks is being used.
To resolve this problem, apply either the cumulative update or the hotfix that is mentioned in this article.

The maximum number of internal TP control blocks for each TI application process is 15,000. When a TI application reaches this limit, the application cannot allocate new APPC conversations.
