Hi Peter,

Thanks for the detailed information. I've not been able to access the
large log, but find some interim suggestions/observations inline:

It may well end up being related to this error:

Did these errors appear  near the same time?

Can you please confirm the hash of this file? I get a bunzip2 data
integrity error when decompressing.

You probably need a larger disk free limit.

You could try a lower vm_memory_high_watermark. If you have very fast
publishers then it is possible for available RAM to be consumed faster
than the broker can react.

The latest version is generally preferred.

To the mailing list, as you have done. Thank you.

Thanks, but it is even more useful to be able to reproduce issues. The
error starting "Absurdly large distribution" has been reproduced. Please
see if my suggestions solve the other problems.
