APAR status

  • Closed as program error.

Error description

  • Using Application Discovery Connect for Mainframe 5.1.0.5, the
STC suddenly began using a very large amount of CPU, in the
period of an hour it used +/- 2380 CPU seconds.

The task done on AD server side during this event wasloading the

Application discovery projects with DB2 and other sources.

Local fix

  • n/a

Problem summary

  • This problem was caused by a bug in the existing code that
mis-interpreted a TCP/IP return code.  The bug was dormant until
 the new communications layer was added in v5.1.0.5

Problem conclusion

  • The bug was caused by a failure to save registers properly in a
subroutine.  After this was corrected the problem was resolved.
Fix is available in AD Connect for Mainframe v5.1.0.7.
