Description Andrew Stitcher 2008-10-28 22:13:52 UTC

Description of problem:
When creating a federation link over an Rdma transport link a connector object is created which is very quickly forgotten. This causes a leak of some 10s of bytes every time a connection is made.

This could be a problem for a very long lived broker, or one that has federation links coming and going a lot.

A very old bug!  Please close if it is no longer relevant.

Comment 4 Andrew Stitcher 2012-11-28 18:46:01 UTC

I think this bug is still present, perhaps not relevant as I doubt anyone is doing federation over rdma. I don't have regular access to rdma hardware anymore so it's hard to check.

A joke or a bug?
May I fix it?
It's maxframesize related, broker will reject the connection with maxframesize=65536, 65536 = zero.

Comment 6 euroford 2015-01-05 06:06:03 UTC

I have fixed this bug，send and receive 1M 20MB messages without any problem.
may i upload the patch?

Comment 7 Andrew Stitcher 2015-01-05 18:57:45 UTC

I don't understand what information you are requesting of me.

Huh, is this a rhetorical question? an insult?

> May I fix it?
Sure.

I can't see any connection between what you just said here and the bug I reported. But it has been a long time since I worked on this code so I may be mistaken (6 years).

Of course you can upload a patch. (I'm trying to understand what circumstances would lead you to ask this question).
