- **status**: unassigned --> invalid
- **Comment**:
The symptoms indicate a performance problem with the setup of resources vs
load for this test.
The test & setup manages to get sync (plus presumably other trafic ?) to
overload fevs.
OpenSAF currently has no overload protection or load regulation so
overloading the system will inevtiably cause degeneration of service.
Here this results in the failure of a sync.
This should lead to the joing paylod retrying the sync.
If the 3rd/4th payload always fails to join it means this resource and
load configuration can not support more than 2 SC and 2 payloads.

** [tickets:#1072] Sync stop after few payload nodes joining the cluster (TCP)**
**Status:** invalid
**Milestone:** 4.3.3

Communication is MDS over TCP. Cluster 2+3; where scenario is
Start SCs; start 1 payload; wait for sync; start second payload; wait for sync;
start 3rd payload. Third one fails; or sometimes it might be forth.
There is problem of getting more than 2/3 payloads synchronized due to a
consistent way of triggering a bug.
The following is triggered in the loading immnd causing the joined node to
timeout/fail to start up.
