Hi,
I use EpiOAuth for my Twitter dashboard application hosted on a
dedicated server, jmathai's async cURL Twitter class, memcached for
caching responses.
Almost every day, more frequently past days/weeks, my server logs API
errors that literally drives the site down, requiring the server to be
restarted in order to be accessible again. It looks like async cURL
doesn't stop for a client after a few seconds due to API
unavailability, but it continues to run until it receives something,
most likely after other connections have been requested, filling the
queue.
Since my application is kneed almost every time these API errors
occur, I would like to know if anyone experiences the same problems
and if you know any workaround or a solution to cURL blocking server
with requests.
For Twitter support, please let me know how should an app handle these
errors best, I am opened to any suggestions.
Frequent errors are:
