Local fix
Problem summary
USERS AFFECTED: All users of the TN3270 Server feature. PROBLEM SUMMARY: A TN3270E client has issued a large number of SYSREQ keystrokes, hundreds of them, while in receive state waiting on data from the host application. When data is received, the TN3270 Server attempts to process all of those SYSREQs and exceeds the available stack space.
Problem conclusion
Internal processing has been modified to generate only one LUSTAT request to the host (which maps to a negative response to report the loss of the presentation space integrity) when the SYSREQ key is pressed multiple times on the tn3270 client.
Temporary fix
