Opened: Jul 02, 2018

Severity: 4-Minor


Two ACL BLOB files are saved in /var/pktclass/ directory in order to provide ACL persistence in the case of BIG-IP system restart. For large ACL configurations, these files can require more space than available on some platforms.


Blob compilation fails.


Large ACL configuration.


Reallocate filesystem, so /var volume can accommodate two large BLOB files. This workaround may be not available on some platforms.

Fix Information

Only one BLOB file is saved in /var/pktclass/ directory. Filesystem reallocation is never required.
