Cisco Bug: CSCta20974 - Counter is needed for timeout and queue full cond. for TCP reassembly
Feb 22, 2014
- Cisco ACE Application Control Engine Module
Known Affected Releases
Symptom: ACE may silently drop out-of-order TCP packets if it receives a large number of outstanding out-of-order segments. That is, for a particular connection, if TCP packets are dropped on the network prior to reaching the ACE and the ACE receives a large number of subsequent packets before receiving the retransmitted packets that were lost, ACE may silently drop the out-of-order segments already received. This issue typically results in connection timeout errors between the ACE and backend server. Conditions: This issue can occur when the ACE processes a large amount of traffic, typically in the form of large file transfers, and the packets arrive at the ACE out of order on the client side due to packet loss on the network.
