actually we are doing some forwarding of events from 10000+ client PCs to a syslog server via eventlog forwarding on a W2k19 servers. No IIS is involved just subscription via GPO configuration The forwarding works.....so far Actually the system drive gets filled up with httperr12345.log files under C:\Windows\System32\LogFiles\HTTPERR The entries are stating: .....5985 HTTP/1.1 POST /wsman/subscriptions/53270844-DA18-48AE-868D-4BC3498E5DAA/5 - 503 - QueueFull
In the perfmon I see 3 queue instances for the HTTP Service Request Queue object one of which is constantly having 1000 objects in the queue. That seems to be a default value for the counter "currentqueuesize"
I cant do an: Set-ItemProperty IIS:/AppPools\DefaultAppPool -Name QueueLength -Value 5000 because we don´t have AppPools and no IIS at all installed. I already found some registry settings for http.sys https://learn.microsoft.com/en-US/troubleshoot/developer/webapps/iis/iisadmin-service-inetinfo/httpsys-registry-windows or https://www.vb-net.com/AspNet-DocAndSamples-2017/aspnetcore/fundamentals/servers/httpsys.htm
but these are not in the registry by default and none of it seems to relate to the queue limit.
In the IIS gui the parameter is queue size https://learn.microsoft.com/de-de/archive/blogs/brenle/modifying-the-queue-length-for-exchange-app-pools-in-iis
Anyone knows the registry key for increasing the currentqueuesize?
