I am running a process on RedHat 7 which uses intensively protobuf.
Application is multithreaded and usually runs wihout problems for days. It
processes billions of messages per day.
Once in a while the program gets aborted. My gdb on core tells that the
abort was initiated in protobuf generated file.
Here is bt output from gdb
#0 0x00007f4a72129377 in raise () from /lib64/libc.so.6
#1 0x00007f4a7212aa68 in abort () from /lib64/libc.so.6
#2 0x00007f4a7216bec7 in __libc_message () from /lib64/libc.so.6

#
On this stack the file /MIObjectSetTypeProtos.pb.h is generated by protobuf
line 794 points to value_.SetNoArena in function below.
inline void MIObjectItemType::set_value(const char* value) {
GOOGLE_DCHECK(value != NULL);
value_.SetNoArena(&::google::protobuf::internal::GetEmptyStringAlreadyInited(),
::std::string(value));
//
@@protoc_insertion_point(field_set_char:interfaces.MIObjectItemType.value)
}
I realize that it can be some memory corruption on my side.
But I still hope that may be somebody from protobuf experts can have
enlightening ideas of how to solve this issue, or somebody remembers
similar situation.
Looking forward to any help.
