Server node not available, operation has timed out.
I have 2 server running couchbase server. Both the server have the same specification and operating system. The difference is one of the server internet explorer is updated to IE10 the other still used IE9.
Full specification is as mention below :
OS = Windows Server 2008 R2 64bit
Proc = Intel Xeon 1.6Ghz
RAM = 16GB
Couchbase Server = 1.8
Couchbase Client = .Net 1.1
The first server is for production (18.104.22.168 ,IE9), the other one is for backup (22.214.171.124, IE10)). I have couchbase client application that run on each server.
The problem is there are intermittent error that happen only on server 126.96.36.199. never happen on server 188.8.131.52. the error are :
"ERROR2013-04-07 17:18:54 –  - HB: Node 'http://127.0.0.1:8091/pools/default' is not available.
System.Net.WebException: The operation has timed out.
at System.Net.ConnectStream.Read(Byte buffer, Int32 offset, Int32 size)
at Couchbase.MessageStreamListener.Heartbeat.Worker(Object state)"
What i don't understand is the couchbase client and couchbase server are in the same pc. so their connection must be local right? is it possible in a local connection the timeout error occured ? And why only happen on server 184.108.40.206 ?
I even try install couchbase server 2.0 to server 220.127.116.11, but the error still occured :(.
Thanks for the assistance.
