I have been having this persistent issue over the last couple days where our application starts 'hanging' and a bunch of requests start timing out. I am still trying to figure out the root cause but I have noticed something strange with coldbox. On this server there are multiple coldfusion applications running and one of them is an API built using coldbox. I am using logbox to log some data to a file and it seems there is this thread that relates to logbox and gets stuck forever. I have included a screenshot from fusion reactor. Hopefully some can point me in the right direction.

Am I reading that right, that the majority of the time (96.6%) is in CFPage.Sleep()?

It seems like it. If I kill the thread, it starts right back up and I dont know why?

what type of appender are you using with logbox?

@Scott Steinbeck thanks. I solved the issue in my other thread in the cfml general channel
