Symptoms

The /var/log/oblog.log.* files are not purged periodically, which might result in a huge numbers of files in the directory.

Impact

ASDK log files might fill disk space and the number will grow unbounded.

Conditions

APM AAA Oracle Access Manager (OAM) SDK is configured and EAM plugin is enabled on any virtual server. When EAM plugin makes Oracle SDK API calls, log messages are generated and written to /var/log/oblog.log.

Workaround

1. Follow the instructions in this DevCentral article to reduce the ASDK log level https://devcentral.f5.com/questions/obloglog-not-rotating-and-it-is-filling-var-log (requires login). 2. Delete older /var/log/oblog.log.* files from the BIG-IP system manually.
