I could not find any reason in the log files that explains why the upload of the symbols would succeed but the unziping of the uploaded file would fail. As a result the symbol information for most of our own symbols were missing. After a manual extraction I can see at least most of the libmerged symbols being resolved when I call minidump_stackwalk manually on the server. However, the mentioned symbol information issue still remains and in some cases where the top level stack frame is in a system library we still miss some resolved stack frames.
