+Sometimes the LiteMage warmup may hang in the Magento system scheduler.
-If you go to Magento Admin -> Scheduler -> Scheduler Timeline, you might see a long cross line for ''litemage_warmup_cache'' either in red or orange color, it actually means the cron hangs instead of running ok.
+If you navigate to **Magento Admin > Scheduler > Scheduler Timeline**, you might see ''litemage_warmup_cache'' highlighted either in red or orange. It means the cron is hanging and is not running propery.

+These results mean that the warmup did begin to run, so we know it works when started manually. A ''Run now'' action won't fix the Magento system scheduler problem, however, and the initiated cron will be stopped due to exceeding the defined **Maximum Run Time** in the configuration.

 ===== Warm Up for logged in users =====
 Normally logged in users and non-logged in users will share the same cache copies. However, when you enable **Separate Cache Copy per Customer Group** in LiteMage configuration, LiteMage will have different cache copies.
