We are stuck on an issue/crash seen within the gRPC library and was looking
for some assistance.
Background:
We are working w/ gRPC v0.12. Given when we started and our release date
we are stuck w/ this version 0.12.
We have plans to move forward to release 1.0 in our next release cycle.
So for now we are stuck w/ v0.12. Given this we are observing a crash
within gRPC library when sending large messages.
Generally anything larger than 10MB. The problem appears after some time
but consistently seen.
Crash is observed at the client side who is pushing the data.
The crash happens due to an abort in the
src/core/transport/chttp2_transport.c: 527.
Crash happens during a destroy stream call.
TelemeterySend GPB status error 4
E0919 08:46:04.117800251 11696 chttp2_transport.c:527] client stream
231 still included in list 9
Aborted (core dumped)
Below is the proto service for the RPC
service gRPCConfigOper {
// TelemetrySend Service
rpc TelemetrySend(TelemetryMsg) returns(TelemetryMsgReply) {};
}
I found few items online that seemed relevant, however it just points to
13.1. The last one listed appears to have dependency on code present
in 13 which is not found in 12.
The 2nd link appears to discuss very similar problem, but not clear if and
how it was resolved ?

Questions:
1. Can you shed some light if this is a known issue that was indeed fixed
and if so what would be required to have this working in 0.12 ?
2. Can you shed some light on the error itself or reason for the abort ?
3. Is there any workaround ? Known limitations on message size in 0.12
which the application can enforce ?
Any assistance or guidance would be appreciated
Thanks in advance.
