    I did a sendrawtransaction on the GUI debug console during pretty heavy lock contention (blocks were being verified) and it seemed the debug console hanged. I tried the same sendrawtransaction again, but no response. Waited quite a long time, but even after blocks were verified there was no response.

    Shutting down, the application seems to hang forever.

    Full output from thread apply all bt here: https://0bin.net/paste/c4FhLI3Yv-OKnCVl#hJBzbgTb1sr+EYnETV4pH1NkTySGfWtsHDQ-C7YQZUW If you need any other information let me know, I'll keep the gdb session open for now.

    Looks like a RPC thread is hanging on https://github.com/bitcoin/bitcoin/blob/master/src/rpc/rawtransaction.cpp#L977 This was introduced in cb06edf938302166030db19017c27889ea5b10b6 (#10286). Running master as of d080a7d. @TheBlueMatt any idea?

    Hmm, did you call sendrawtransaction on a transaction already in your mempool? If so #11738 should fix the issue.

    Yes, the transaction was already in the mempool. Thanks!
