# Timeout issues when replying on comments

 * Recently I get a lot of timeout issues when replying to comments. It takes a 
   lot of time to process a reply and I often get a 504 error, or even a complete
   Connection lost due to a database error.
 * Now the first thought is of course that this is a server issue, but even after
   upgrading the server, the problem remains. The problem also only occurs when 
   replying to comments.
 * I did found the following error in the log:
 * `Got error 'PHP message: PHP Fatal error: ob_start(): Cannot use output buffering
   in output buffering display handlers in /domainname/public_html/wp-content/plugins/
   subscribe-to-comments-reloaded/templates/request-management-link.php on line 
   101'`
 * I currently have over 6500 comments and probably way more then 1000 subscribers(
   table is maxed out).
 * Any thoughts on what the issue could be? I am a bit hesitant to disable to plugin
   to test replying to comments without it, for the risk of losing the subscribers.

 * Hi,
 * > and probably way more then 1000 subscribers
 * You can view the total number of subscribers and subscriptions in WP admin > 
   StCR > StCR System. You’ll see the “System Information” area, below that is an
   error log (empty if logging disabled) and below it “Plugin Info” with those numbers.
 * It’s possible that there are too many subscriptions so it’s hitting a limit.
 * The emails are sent out immediately after the comment is approved, there’s no
   built-in email queueing system. It would be helpful in cases of large amount 
   of subscriptions, I’ll add that on the to do list but at the moment I can’t say
   for sure when that feature might be implemented.
 * There are some plugin which do that, they might work out in this case.
