Hi,
Please see my question at the end of this mail...
Our customer run strobe report and found that CEEVGTSI took 55% CPU:

CEEVGTSI is called from many places of our BASE module. The product uses
multothread architechture, it receives TCP/IP requests and moves them to
CICS via EXCI.

My question is: may the large number of Get heap requests cause such
problem? If not, what the problem may be?
