[rabbitmq-discuss] Frame Errors

Mon Oct 12 21:18:04 BST 2009

Hey all. I'm running into an issue with my rabbitMQ server. I have an
inkling of what the problem might be but I wanted to run it by you folks.
Some background, I'm running rabbitMB 1.6.0
[{running_applications,[{rabbit,"RabbitMQ","1.6.0"}, {mnesia,"MNESIA CXC 138
12","4.3.5"}, {os_mon,"CPO CXC 138 46","2.1.2.1"}, {sasl,"SASL CXC 138
11","2.1.5.1"}, {stdlib,"ERTS CXC 138 10","1.14.5"}, {kernel,"ERTS CXC 138
10","2.11.5"}]}, {nodes,[rabbit at neutrino]}, {running_nodes,[rabbit at neutrino]}]
I'm using the Java client. I have an app that basically takes the Twitter
firehose, throws every link it gets into an exchange, and that exchange
throws the links to different bins depending on what the links are and who
they're from. So the routing keys are typically [twitter_user_id].[link]
(e.g. 1022101.http://google.com). Everything has been running wonderfully,
but I recently noticed that rabbitMQ has been throwing frame errors every
now and then. I have a sneaking suspicion that this is related to unicode
characters in certain tweets (usually foreign language tweets). Would the
fact that it's trying to run a binding check on an extremely long key be the
cause for these errors? If not, what else might be the issue? Here's the
error report for one of the crashes: =CRASH REPORT==== 6-Oct-2009::02:13:25
