I have very long running instance of the Web server... running for months and months with pretty steady access. For instance, the DrDr Web app never needs to be restarted.
I don't want to be too dismissive of questions like this, but I haven't noticed what you're talking about as being rooted in the server itself. (Every once in a while I discover little things that could be the root of problems like that. For example, there was an additional thread per connection that was removed before the last release.) As for things going on in servlets, it can be easy to make continuations too big (but you say you're not using them). It can be easy to leave the server side connection hanging, I'd use lsof to see if that's the case. I'd say the first thing to do is gather data... such as the output of 'uptime' and memory usage of the server and the servlet (using current-memory-use)... until you get a crash Jay On Wed, Apr 10, 2013 at 12:10 PM, Danny Yoo <d...@hashcollision.org> wrote: > I wanted to check with other folks to see if anyone else has been > having problems with long-running instances of PLT web server.
