How do I prevent server timeouts on Lite Speed?

(The article below is specifically for customers running on Lite Speed.  For general information about Threadloom and timeouts, view this article.)

To avoid Lite Speed server timeouts when communicating with Threadloom, you need to make sure there is enough headroom with LSAPI_MAX_PROCESS_TIME and your connection timeout.

Change LSAPI_MAX_PROCESS_TIME

By default, the LSAPI_MAX_PROCESS_TIME environment variable is set to 3600 seconds, which is sufficient for Threadloom to sync your index.  However, if you've set this to a low value, we recommend changing this value back to the default value of 3600 seconds.  You can find this in WebAdmin CP > Configuration > Server (or Vhost) > External App > <your external application> > Environments.  The value should be set as follows:

LSWS LSAPI_MAX_PROCESS_TIME = 3600

Configure Connection Timeout

If you are running Lite Speed, you can set a longer timeout in WebAdmin CP > Configuration > Server > Tuning > Connection Timeout (secs).

If you prefer to set the connection timeout specifically for Threadloom, you can either add a virtualhost directive or update your .htaccess files.

Alternate option 1: Add a virtualhost directive

Add the following HTTP and HTTPS directives to your virtualhost configuration file:

<IfModule LiteSpeed>

RewriteEngine On

RewriteRule ^/deferred\.php - [E=noabort:1, E=noconntimeout:1]

RewriteRule ^/library/Threadloom/.* - [E=noabort:1, E=noconntimeout:1]

</IfModule>

(For general information on regex in rewrite rules, we recommend this article and this article.)

Alternate option 2: Update your .htaccess files

Update the .htaccess files in the following 3 locations:

/<path to forum home folder>

RewriteEngine On

RewriteRule deferred.php - [E=noabort:1, E=noconntimeout:1]

/<path to forum home folder>/library/Threadloom

RewriteEngine On

RewriteRule Sync.php - [E=noabort:1, E=noconntimeout:1]

/<path to forum home folder>/library/Threadloom/common

RewriteEngine On

RewriteRule Syncer.php - [E=noabort:1, E=noconntimeout:1]

Note: On servers with very limited resources, it is possible that making these .htaccess changes may impact server load/capacity.
