[openib-general] getting many (4/5 of the time) RDMA_CM_EVENT_ROUTE_ERROR

[Or Gerlitz]

Hi Sean, Hal

Since updating to 2.6.16 and drivers/infiniband replaced by openib svn trunk 
r5919 i am getting ETIMEDOUT (-110) cma event on the iser initiator side, 
about 4/5 of my reconnect tries.

> iser:iser_cma_handler:event 0 conn ffff81003ee0be20 id ffff81007cd8e2f0
> iser:iser_cma_handler:event 3 conn ffff81003ee0be20 id ffff81007cd8e2f0
> iser:iser_cma_handler:event: 3, error: -110

Each time i get RDMA_CM_EVENT_ADDR_RESOLVED, so there's IB connectivity
but then the path query failed.

I have not digged yet much into that, so i don't know if there's any
issue at the SM/SA side (Voltaire SM/SA), will do that tomorrow.

Just curious, was there lately any change in along the cma/local-sa/rmpp/mad 
layer chain that possibly might broke something? I recall there was a 
change in the rmpp code, could it break something with the voltaire rmpp 
impl? i guess you have some synthetic test for RMPP, can i get it? (and 
some info how to run it...)


Or.
