Trying to recreate an issue which lock CPU on server into 50% usage .Been told it looks like its some ASP code thats looping !
Not manging to recreate the circumstances that causes it at all so not manging to narrow it down .
A temporary cure to keep the server fast is we have adjusted the RECYCLE WORKER PROCESSES to 1 hour , instead of its previous 29 hours !
This does not seem to have any effect adding to cart or any negative effect on customer browsing ..would you agree , cn we safely leave at one hour ?

Doesn't the recycle worker process clear out all sessions? If it does then this would cause a problem.

i agree if the sites ( vpasp 6.5 ) were running in session mode, cookieless mode ! but they are not
If we add to items to cart and recycle, the items still stay in cart . i am unaware of anything else doing this may effect ..for the moment its keeping the server fast but not the ultimate solution
Any advice on WHY recycling worker processes would be bad in these circumstances would be appreciated , as we cant find any negatives to it as of yet.
Further any advice on software that can help monitor WHY the CPU is locking into 50% usage would be appreciated , some times this is happening within 20 minutes of a RWP reset and before the 1 hour reset was implemented within hours the CPU was hitting 100% causing all browsing to crawl to a halt. IS the a way of tracking what could actually be causing this possible loop?

still having this issue and looking for ideas ! thoughts on what might be causing ........
I am running vpasp MULTIPLE SHOPS and the sites are cross linked im wondering if its something to do with sessions being left open ? sites are on own domains ..but all products come from one database , each shop has its own configuration table
IE ..customer visits shop A , browses a bit then spots a link to shop B ...goes to shop B , browses a bit then goes to shop C ...
can anybody imagine would this would create issues with very high CPU usage ?
Appreciate any feedback

Using a software called process monitor i can see the processes that are running on CPU , its very indepth though and for someone like myself theres tooo much info ...one thing that stands out is this section that seems to repeat and be active MULTIPLE TIMES PER SECOND , even when theres no active visitors ...does it mean much to anyone ?could this be the problem ?

hi; I must have missed a notification email from an update on the ticket; I'll have a look for it and investigate, it might be that you need a newer version of the addon; I'll check it out.

I've had a look; my guess is that it's something to do with the images being sourced from another server at runtime, so the sizing/defaulting can't load it to check its size/existence; it's possible that the loadpicture command hangs if it can't find/access the server.
