Issue/Introduction

When trying to run log streams logged from production with many terminals (i.e. more than 1000), the following messages are generated: 

DFHAC2236 07/21/2015 05:06:40 A25ICIC1 Transaction XTCA abend CORE in program XTCAMAIN term C014. Updates to local recoverable resources will be backed out.

and

+DFHSM0133 A25ICIC1 CICS is under stress (short on storage above 16MB)

 

Environment

Release: OSVERW00200-8.5-Verify-Automated Regression Testing-for VTAM Extended Environment

Resolution

To resolve this problem you will likely have to increase the EDSALIM parameter.

That means when logging a large number of terminals this will also need to increase the size of the CICS SIT parameter EDSALIM.

For example, EDSALIM=64M likely won't be enough for 1000 terminals, but EDSALIM=96M should be enough in this case.
