The operation has timed-out & Web Service

[Guest]

I've faced one cunning problem recently: I'm using IIS 6.0 as a web server,
running on 1.1 framework. When i'm accessing my .net web service all goes
fine, until I receive "The operation has timed-out." exeption after some time
of usage. After such occurence all futher calls to web service result in
exception of the same kind. I've tried overriding proxy-class with removing
keep-alive and also switched keep-alive off at the server-side but without
any visible effect.

Any ideas?

Thanks in advance!

Are you writing anything to event log?

I remember I had this problem before, end up the problem was that the event
log is full, just changed the setting in the event log then it worked fine
again.

don't know if this can slove your problem, try it.

I've also found this in IIS 6.0 Server Log:

2006-06-01 18:56:58 10.0.0.220 POST /LxServiceStateServer/DataServices.asmx
- 80 - 10.0.0.71 HTTP/1.1
Mozilla/4.0+(compatible;+MSIE+6.0;+MS+Web+Services+Client+Protocol+1.1.4322.2032) 200 0 64 25 678

The strange thing here is that the http status code is 200 (seems to be
fine), yet the win32 status code is 64 (something strange here =)



And here is the tcp trace from the client side:

Seems that after 64 error it is impossible for client to resolve server name
neither read/write from socket, neither create new sockets to work with the
current server unless the client application is completely restarted.
