[rabbitmq-discuss] bug21673 crashed with very large transaction

[mabrek]

Hello.
I've got a crash with new persister and very large transaction. How to
reproduce: open transaction and send large amount of messages without
committing it. Rabbitmq process will use all available memory and then
crash. I tried to send 2000000 messages, but rabbit died at 800000.

Interesting pieces from rabbitmq.log:

alarm was set and cleared several times.

startup_err contains:
