Fixed In:

Opened: Sep 14, 2021

Severity: 3-Major


While performing OCSP authentication, the APM log file (/var/log/apm) shows the incomplete path of the OCSP URL.


Incomplete path of the OCSP URL causes ambiguity and gives the impression that APM is not parsing the URL correctly, while LTM parses correctly at the same time.


-- Configure OCSP Server object -- Configure OCSP Agent in the VPE -- Perform OCSP Authentication



Fix Information

The APM deamon parses the given OCSP URL correctly but while printing it in the logs the apmd is reading it partially due to limited log buffer size. The log buffer size is increased to print the complete OCSP URL paths.
