Issue:

After installing CA Spectrum 10.2.1, false alarms are generating and clearing on pingable, UIM hosts and Access Point models.  When the model is polled, a successful response is received.  When reviewing the events, you will notice that the alarm may be generated and cleared within the specified timeouts (DCM retry and DCM timeout). The following is an example:

"Critical","Apr 9, 2017 5:32:18 AM EDT","arcade1","Device arcade1 of type UIMHostServer has stopped responding to polls and/or external requests.  An alarm will be generated.","System","Apr 9, 2017 5:32:20 AM EDT","System","0x10d35"

Critical","Apr 10, 2017 1:03:04 PM EDT","arcade25","Device arcade25 of type AccessPoint has stopped responding to polls and/or external requests.  An alarm will be generated.","System","Apr 10, 2017 1:03:04 PM EDT ","System","0x10d35"
Environment:
Spectrum 10.2.1
Cause:

There was a code flaw in the way Spectrum was handling Pingable model communication in 10.2.1.

Resolution:

This is resolved in patch 10.02.01.PTF_10.2.103  for CA Spectrum 10.2.1 with the following details in the Release Notes.

Additional Information:
NOTE: Residual data associated to the affected models means that they need to be destroyed and rediscovered. The patch will prevent new instances of the problem but will not clear already existing instances, even after the SpectroSERVER is restarted.
