Hi all,
I have a critical issue I am using CRM 2015.Most of my workflow system jobs giving me status "waiting for resources" , and number of these workflows increase till it causes system freezing .
This issue was repeating monthly but now it repeats every 15 minute.Every time the system works after restarting the ASYNC services and I run a script and I attached it within this post but it is hard and waste time to make restart for system every 15 minute.
I want to know what is the reason for entering workflows in "waiting for resources" status and how can I solve this issue ?
Thanks in advance
