Hi all,
I think the default 500 connections are hard-coded, even in qpid-0.10:
-- where the log appears from:
cpp/src/qpid/broker/ConnectionFactory.cpp:45: QPID_LOG(error, "Client
max connection count limit exceeded: " << broker.getOptions().maxConnections <<
" connection refused");
-- where the variable is initialised:
cpp/src/qpid/broker/Broker.cpp:107: maxConnections(500),
cpp/src/qpid/broker/Broker.cpp:197: connectionCounter(conf.maxConnections),
-- how the property is configurable (Alan Conway mentioned this earlier):
cpp/src/qpid/broker/Broker.cpp:142: ("max-connections",
optValue(maxConnections, "N"), "Sets the maximum allowed connections")
Kind regards,
Pavel

Subject: Re: Qpid c# client - 500 connections problem
Hi Chuck,
unfortunately the erros all occur localhost under Win XP 32bit with qpid 0.10
as c# client AND 0.10 c++ broker.
I try to install qpid under linux ... although i think there must be another
problem.
