Re: [openflowplugin-dev] openflowjava IOB Exception in netvirt csit

Hi Jamo,


can you please try if this issue also occurs with single-layer serialization disabled? Here is link to wiki on how to disable it: https://wiki.opendaylight.org/view/OpenDaylight_OpenFlow_Plugin:OF13%2B_Single_Layer_Serialization#Enabling.2FDisabling_Single_Layer_Serialization

Also, can you send dump of flows (or ideally only that single flow that is failing when OFP is tryining to deserialize it) from ovs?


Regards,

Tomas

Predmet: [openflowplugin-dev] openflowjava IOB Exception in netvirt csit
 
Hi OFP, OFJ, Netvirt,

I'm debugging some failures in netvirt CSIT and saw an exception I don't remember
seeing before (not that it's new, I just haven't seen it. although I dig at these
things daily)

2017-05-09 15:52:45,124 | WARN  | entLoopGroup-7-5 | OFDecoder                        | 268 -
org.opendaylight.openflowjava.openflow-protocol-impl - 0.9.0.SNAPSHOT | Message deserialization failed
java.lang.IndexOutOfBoundsException: readerIndex(166) + length(4) exceeds writerIndex(166): UnpooledSlicedByteBuf(ridx: 166,
widx: 166, cap: 166/166, unwrapped: PooledUnsafeDirectByteBuf(ridx: 13896, widx: 13896, cap: 16384))

There are a lot of them (~1200) over a 90m system test job.

I don't know yet if they are related to the failures I am debugging, but something is not right.

Any comments? Need a bug?

here is the full karaf log:
