Hi ,
I am seeing following a crash in grpc code. I have 5 node setup, where all
nodes are streaming out data. After few hours of streaming, I am seeing a
crash on 2 nodes but rest 3 nodes are working fine. It is not always
reproducible. Looks like some timing issue. Below is the crash :
#0 0x7438e660 in __GI_raise (sig=sig@entry=6)
at ../nptl/sysdeps/unix/sysv/linux/raise.c:67
#1 0x743900ae in __GI_abort () at abort.c:92

WaveGrpcClientInfo<com::telemetry::interface::InterfaceStatisticsProfileResponse>::postDataToClient
(this=0x9ad64a0, pdata=0x72611028,
deleteProtoBuf=false) at ./GRPCInterface/WaveGrpcClientInfo.cpp:47
Env Information:
- cpp server
- python client
- grpc library version : 1.1.0-dev
- Asynchrous streaming
Code :
template <class T> void WaveGrpcClientInfo<T>::postDataToClient (void
*pdata, bool deleteProtoBuf)
{
//check if client is still alive, if client is disconnected, just
return.
if (m_serverContext->IsCancelled ())
{
return;
}
// post the protobf output to client.
m_writer->Write (*(static_cast<T*>(pdata)), m_uniqueTag);
if (true == deleteProtoBuf)
{
WaveNs::tracePrintf (TRACE_LEVEL_DEVEL,
"WaveGrpcClientInfo::postDataToClient: Deleting payload.");
delete ((static_cast<T*>(pdata)));
}
}
ServerAsyncWriter<T>* m_writer;
Is this a known issue ? is it fixed in any newer release ? Please help.
Thanks
Chaitanya
