Systems and methods for server crash prevention

Abstract

Disclosed are methods, systems, and computer-readable medium for preventing system crashes, including loading a resource from a real resource location; receiving a registration request from a resource user; registering the resource user by updating a resource owner registration list to indicate the resource user registration; receiving a first unload request and determining that the resource user is registered by accessing the registration list; upon determining that the resource user is registered, denying the first unload request; generating a stop use request; transmitting the stop use request to the resource user; receiving a deregistration request from the resource user, based on the stop use request; deregistering the resource user by updating the resource owner registration list; receiving a second unload request after deregistering the resource user; and approving the second unload request to unload the resource.

         21 . A system comprising:
 at least one memory storing instructions; and   at least one processor executing the instructions to perform operations, the operations comprising:
 receiving a first unload request for a resource; 
 determining that a resource user is registered for the resource; 
 upon determining that the resource user is registered, denying the first unload request; 
 receiving a deregistration request from the resource user; 
 deregistering the resource user; 
 receiving a second unload request after deregistering the resource user; and 
 approving the second unload request to unload the resource. 
   
     
     
         22 . The system of  claim 21 , further comprising:
 upon denying the first unload request:
 generating a stop use request; and 
 transmitting the stop use request to the resource user. 
   
     
     
         23 . The system of  claim 21 ,
 wherein registration or deregistration of the resource user is by updating a resource owner registration list, and   wherein updating the resource owner registration list comprises modifying a binary value associated with the resource.   
     
     
         24 . The system of  claim 21 , further comprising deleting the resource from the resource user after deregistering the resource user. 
     
     
         25 . The system of  claim 22 , wherein the stop use request is generated based on a project unload. 
     
     
         26 . The system of  claim 22 , wherein the stop use request is generated based on an cleanup operation. 
     
     
         27 . The system of  claim 22 , wherein the operations further comprise:
 receiving a resource use request at the resource user;   determining that the stop use request has been received at the resource user; and   denying the resource use request.   
     
     
         28 . The system of  claim 27 , wherein the deregistration request from the user is based on denying the resource use request. 
     
     
         29 . The system of  claim 22 , wherein the operations further comprise:
 receiving a resource use request at the resource user;   determining that the stop use request has not been received at the resource user; and   denying the resource use request.   
     
     
         30 . A system comprising:
 at least one memory storing instructions; and   at least one processor executing the instructions to perform operations, the operations comprising:
 receiving a first unload request for a resource; 
 determining that a resource user is registered for the resource; 
 upon determining that the resource user is registered, denying the first unload request; 
 determine a null use of the resource by the resource user; 
 deregistering the resource user, based on the null use; 
 receiving a second unload request after deregistering the resource user; and 
 approving the second unload request to unload the resource. 
   
     
     
         31 . The system of  claim 30 , wherein null use of the resource by the resource user is determined by accessing a use log. 
     
     
         32 . The system of  claim 30 , further comprising:
 upon denying the first unload request:
 generating a stop use request; and 
 transmitting the stop use request to the resource user. 
   
     
     
         33 . The system of  claim 30 ,
 wherein registration or deregistration of the resource user is by updating a resource owner registration list, and   wherein updating the resource owner registration list comprises modifying a binary value associated with the resource.   
     
     
         34 . The system of  claim 30 , wherein the operations further comprise deleting the resource from the resource user after deregistering the resource user. 
     
     
         35 . The system of  claim 32 , wherein the stop use request is generated based on a project unload. 
     
     
         36 . A system comprising:
 at least one memory storing instructions; and   at least one processor executing the instructions to perform operations, the operations comprising:
 receiving a first unload request for a resource; 
 determining that a resource user is registered for the resource; 
 upon determining that the resource user is registered, denying the first unload request; 
 determining that the resource user is in a sleep state; 
 deregistering the resource user, based on the determining that the resource user is in a sleep state; 
 receiving a second unload request after deregistering the resource user; and 
 approving the second unload request to unload the resource. 
   
     
     
         37 . The system of  claim 36 , wherein determining that the resource user is in a sleep state is based on one of a null response or a sleep state status response. 
     
     
         38 . The system of  claim 36 , wherein determining that the resource user is in a sleep state is based on a sleep state instruction. 
     
     
         39 . The system of  claim 36 , further comprising:
 upon denying the first unload request:
 generating a stop use request; 
   transmitting the stop use request to the resource user.   
     
     
         40 . The system of  claim 36 ,
 wherein registration or deregistration of the resource user is by updating a resource owner registration list, and   wherein updating the resource owner registration list comprises modifying a binary value associated with the resource.
