While an application programmer was attempting to debug a large application program, the CICS region hung and needed to be recycled.
The EDSALIM was too small. For CTS/TS 4.1, the default is 34M, this region was set at 42M.
Increase the EDSALIM. The recommendation was to increase it to 90M which resolved the problem.
Refer to the EDSALIM system initialization parameter as described in the IBM Knowledge Center
