Last Modified: Jul 12, 2023

Affected Product(s):
BIG-IP LTM(all modules)

Fixed In:

Opened: Jun 27, 2018

Severity: 3-Major

Symptoms

'invalid class type" error message in /var/log/ltm.

Impact

iRule fails.

Conditions

Using external datagroups and updating them before the previous update has finished, such as with: -- Executing config-sync. -- echo "create sys file data-group dg-test source-path file:///var/tmp/dg_test type string separator :=; create ltm data-group external dg-test external-file-name dg-test; modify sys file data-group dg-test source-path file:///var/tmp/dg_test" | tmsh -a

Workaround

Ensure that changes to a datagroup are done processing (by looking for the 'finished' message in the LTM logs) before updating them again.

Fix Information

Rapid updates no longer cause type corruption.
