Subject [jira] Commented: (AMQCPP-171) futureResponse error when on a slow connection
Date Fri, 07 Mar 2008 00:50:35 GMT


Timothy Bish commented on AMQCPP-171:

I would look at the connection rate and the loading on the system and then try to find a balance
that meets your  particular set of fault tolerance requirements.  A timeout on response could
happen for many reasons, so the answer is to set it at such a level that you are able to detect
an error versus just a slow connection or machine.

if 15000 doesn't make it stable enough try 20000 i.e. 20 seconds

busy. any suggestions ???
