There is no single symptom but several: > * Receivers use all system memory and cache and getting hit by the OOM k= iller > * underrun > * illegal value for field > Research shows that function qdr_forward_drop_presettled_CT_LH is routine= ly dropping presettled deliveries that have already made forward progress i= n transmitting bytes to the wire. After that happens there is a race condit= ion as to whether the message is successfully transmitted or the message is= torn down in the middle of transmission. > For reproducing this error the sender must supply messages significantly = faster than the receiving router can forward them to the next router. This = triggers the presettled drops. My test setup does this by having the sender= and the receiving router on the same laptop and having the next router con= nected over a relatively slow WiFi. > =C2=A0 -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscribe@qpid.apache.org For additional commands, e-mail: dev-help@qpid.apache.org
