Hi ...
We are using EAP5.1.1 (remoting-2-4-5.SP2) and experience a problem when using
SSL and there is a network hard failure (e.g. ethernet cable pulled), a socketWrite0()
hangs
while holding a Messaging Post Office lock (readLock()) - this hangs JMS...(many threads
need PostOffice). Thread dump below. It is difficult to reproduce.
A Solaris 10 environment.
This problem has only been observed when SSL is used.
In our remoting-bisocket-service.xml file, we use:
<attribute isParam="true"
name="writeTimeout">30000</attribute>
Have been told "writeTimeout" is broken when SSL is being used.
It has been suggested, for SSL, we change the configuration to turn on the
check_connection parameter:
<attribute isParam="true"
name="socket.check_connection">true</attribute>
But my concern is:
* results in an extra round-trip I/O (not good for a variety of reasons - throughput,
remote clients with high latency connecitons, etc.).
* potential to hit other problems with check_connections enabled. e.g. found this:
https://community.jboss.org/message/369442#369442
https://community.jboss.org/message/369442
Has anyone experienced this problem and/or know a solution (other then using
"socket.check_connection") might be?
Searched and found a number of remoting issues on hard-network failure, but not this
particular one...
