From the manual:
applid Program interrupt occurred with system task taskid in control
A program check has been detected in a system task. taskid is the system task identifier (for example, TCP, III) as set in field TCAKCTTA.
CICS abnormally terminates with system dump SR0601 and an exception trace entry which gives the kernel error data for the program check.
Use the dump to determine the cause of the program check. The most likely causes are either an error in a CICS module, or an error in a user-written PLT program.
For advice on problem determination, refer to the CICS Problem Determination Guide.
If there were any recent changes to PLT programs, look at them since that's probably the source of the problem. Otherwise, you'll need to contact your site support group and get them looking at the CICS modules.
