Bug Details

Priority: 2-Critical
Status: Not Verified
Impact Category: Local Traffic Manager

Description

Symptoms

This leaves the rule expecting the result of the *prior* table command instead. When that result arrives, it is treated as the result for the CLIENT/SERVER_CLOSED's iRule. This has the effect of both not actually executing the requested table command *and* supplying the wrong result.

Impact

Incorrect iRule operation.

Conditions

Table command does an asynch operation in an iRule on a flow which is aborted.

Workaround

None.

Fix Information

None
