Issue/Introduction

One of our findings is that two of our dev servers post this error messages frequently in the siteminder web agent watrace.log

[08/07/2018][14:50:55][17320][15364][CSmIntroscopePlugin.cpp:454][CSmIntroscopePlugin::EndRequest][000080fe000000002c352ea906c9f4f9-43a8-5b69ea0f-3c04-037f2959][*IP-Address][][clagent][/healthcheck/donotdelete.asp][][Error generating the GUID key. Key was more than 32 characters.]

What does it mean?

How do we get rid of this?

We see these messages on all our new servers and our legacy ones..
Win2012 IIS Webagent 12.32

Environment

Release:
Component: APMAGT

Resolution

The exception which are seen in WebAgent trace has no impact on SSO or APM-SSO. From new APM-SSO 13.0 on wards APMSSO agent is no longer using GUID’s. The exception which is seen in your environment is linked with the default GUID which is sent by APM-SSO from APM-SSO 13.0 on wards to keep backward compatibility of SSM 12.X. APM-SSO agent sends default GUID as "00000000-0000-0000-0000-000000000000". Which is larger than 32 Char. (Consider counting '-' as well ). Thus we see the exception in webagent trace log. There is no impact on any functionality either in SSO or in APM-SSO with this exceptions. 
This issue has been fixed in APM-SSO 13.2 release.
