Thanks all, in advance for your help. While familiar with the ways of the web I am no developer and am humbly reaching out for your help.
We're facing a serious up-time issue with a couple of 2008.5 installs; occasionally connections will slow to a crawl and cause the site to, more or less, shut down. Rebooting the servers (database and site are on separate machines) will bring us back online but in only a few days we're back to crawling/restarting again.
Our community moderators and members are understandably upset and ready to migrate elsewhere. I've explored a change in hosting solutions but don't see any indication through usage reports that the machines or network are the issue.
Our hosting provider recently reported that a crash of w3wp.exe caused the most recent outage—I'm waiting to hear back on a history of this app crashing and any cause, but at this point (and by this dialog, stackoverflow.com/.../common-asp-net-intermittent-hang-ups, which fits our symptoms) it's the most likely lead I've found.
I've reached out to Telligent support who pointed me toward these developer forums for assistance.
• Has anyone else seen similar issues with CS2008.5 or can confirm w3wp.exe is where we need to look for an explanation?
• Are any developers who have addressed this issue available to help?
