WCF 4.0 Service crashes -

-

i have wcf service hosted in iis 7.0. working past year, it's crashing , restarting every few minutes. looked @ trace file, , see error don't know means. tried googling no luck. checked settings in iis. looks ok.

this how trace looks like. if can me understand trace, good.

enter image description here

this pure assumptions, far guess looking @ traces , wrote:

  • you using net.pipe wcf host

  • the endpoint address of host net.pipe://tstwebashitv... something, not using net.pipe://localhost/... format (assuming tstwebashitv not server name, , net.pipe not remote)

  • the service used work long time

so assume there possibility named pipe wcf host running on same machine, , might cause conflict.

that's why suggest check points:

  • have net.pipe endpoints adresses under format: net.pipe://localhost/something instead of net.pipe://something.

  • check hostnamecomparisonmode setting in netnamepipebinding section : better set exact ensure running hosts receives messages addressed them.

basically, if hostnamecomparisonmode not set, strongwildcard default mode used , host name in net.pipe address discarded.

if have net pipe address set 'net.pipe://something', "something" considered server name , discarded. several host running way conflict together.
