> OS: RHEL 8.9
> VCPU: 16
> Total RAM: 64 GB
> Heap allocation (Xmx): 8 GB
>            Reporter: Mayank S
>            Priority: Major

> While performance-testing Ofbiz 18 under high load (200 concurrent users), we have observed an intermittent error, stating "null DispatchContext".
> While doing more analysis, we realized it is a thread-safety issue, and it was fixed by adding the 'synchronized' keyword to the following method signatures in ServiceDispatcher.java:
> public static synchronized getInstance (Delegator delegator) 
> public static synchronized void register (DispatchContext context)
