Hi - I'm running the latest version of DNN (4.8.2) on SQL 2005, IIS 6 on a fairly beefy box (dual, duo-core 2.4GHz, 4 Gigs Ram, etc.). There are no other sites running on this server, and it is NOT in production yet, so at any given time there is only ever 1 or 2 users online.
In the last few days, I've noticed intermittent slowdowns (and complete lockups) of my new site. On the server, the CPU sits nearly idle (0-1% util), Memory is flatlined very low, I/O is very low, and SQL is idling at like 1-3%.
On IIS - I've tried resetting the app pools and even stopping/starting the web service. No effect.
On SQL - I've truncated the logs and have a weekly schedule to re-index all tables, etc. No effect.
On DNN, I've checked all schedules and they don't correspond to the slowdown/lockups at all.
Local Connection: I've checked my local connection and have tried connecting from different places, so it's not my connection to the internet.
I have seen some interesting logs in the event viewer, but none of them correspond to the slowdowns either (I've pasted two very common ones below).
Interestingly enough, I've started getting some popup message that read "Sys.WebForms.pageRequestManager TimeoutException : the server request timed out ."
I'm really scratching my head on this one as I originally thought it might have to do with the service schedule for the forums, but this isn't it.
Any thoughts about this at all? I'm really stumped and could use some expert help on this.
