Re: Read timed out error on web services
There was a known issue where Web service API times out after 40 seconds. This was fixed in 7.5. Please collect API/SQL/Filter logging & check if you see the same issue. What's the default time out set for Plug-in? The fix was provided to use Server-Plugin-Default-Timeout values which was earlier hard coded. I don't think this was fixed in 7.1code line.

Re: Read Timed out error on web services
One thought that comes to mind is increasing the AR Filter Plugin threads. I do not remember off hand what that parameter is but you should find it in the Admin guide under the ar.conf section of the guide. This would help if your time out is because a thread is not available.

Re: Read Timed out error on web services
It appears like you have more of a communication issue with the external web service than a problem with it not working at all - the later which would have been easier to trouble shoot than a sporadic communication issue. Does the error display on the user console? Or is it a error that shows in the arjavaplugin log? If it's an error that displays on the user console, does it have an associated ARERR returned? Where I am headed at is basically filter error handling.. This will not 'resolve' your problem or even help you 'circumvent' it, but will help you not show a meaningless error to the user.

Re: Read Timed out error on web services
Hi, You should also try and use something like Wireshark along with your 3rd party tool, and forward the result of the dump to a network expert when you get this timeout. I bet he will see some incomplete TCP streams or other low level funny things, like packets lost in the wild.
