Post subject: IIS / DFS contents
Archived from groups: microsoft>public>inetserver>iis (more info?)
Hi


I am using a few web server which are getting there content in a DFS
share.
I often have hangs (IIS degug diag only show a Com + sta pile up).
When the system hangs, i get the process system (PID 4) going up in the

task manager and a perfmon show me this counter going up :
redirector/current commands (which is 5 or 6 on one web server, and can

raise to 60 or 100)


I read several thing about this indicator, old helps say this is a
queue of samba commands and seem to say that such an indicator high
means I have to subnet my network and add one or more NICs.
Well in fact, I only have 10 to 20 Mbit/s over this nic (FE in full
duplex, with no error on the switch), I tuned the lanman registry keys
(maxcmds and other one on the file server), but theses value stay quiet

high, and the IIS still sometimes hang when there are unusual GETs /s
on the web server.
Every OS are WIN 2003 SP1 with last public updates.
Any advice would be appreciated,


Regards.


YP.

Here is an example of a d. Diag analysis :

A COM+ STA Activity Pileup has been detected in
w3wp.exe___XXXXXXXX.com__PID__2956__Date__11_08_2005__Time_02_08_34PM__355__IIS
Hang Dump.dmp. There is more than one activity bound to every COM+ STA
ThreadPool thread.



See the COM+ STA ThreadPool Report for more detail. All of the STA
ThreadPool threads are busy processing calls. DebugDiag has detected a
blocking issue or issues in this dump, so the STA ThreadPool depletion
is most likely a symptom of the blocking issue. Review the other Errors
and Warnings in the Analysis Summary section of the report for the
details on the blocking issue(s).
Error A COM+ STA Activity Pileup has been detected in
w3wp.exe___YYYYYY.fr__PID__4672__Date__11_08_2005__Time_02_08_38PM__277__IIS

ThreadPool thread.

ThreadPool thread.



See the COM+ STA ThreadPool Report for more detail. 66% of the STA
ThreadPool threads are busy processing calls. DebugDiag has detected a
blocking issue or issues in this dump, so the STA ThreadPool depletion
is most likely a symptom of the blocking issue. Review the other Errors

Warning The following threads in
w3wp.exe___XXXXXXXr__PID__4672__Date__11_08_2005__Time_02_08_38PM__277__IIS
Hang Dump.dmp are not fully resolved and may or may not be a problem.
Further analysis of these threads may be required.

45,21% of threads blocked

When this happens, i get the System process running with really more
CPU than usual. The more I study this case, the less I think this is an
IIS problem.
