What Does 0xC0000194 Mean?

A potential deadlock condition has been detected. A thread has been waiting for a resource lock for an extended period, suggesting a circular dependency between threads.

Real-World Causes

  1. 1Two or more threads waiting for each other to release locks
  2. 2Application bug with incorrect lock ordering
  3. 3Long-running operation holding a lock while another thread needs it
  4. 4Third-party plugin or DLL introducing lock contention
  5. 5Database or file lock held indefinitely due to an error

Symptoms

  • ⚠Application freezes completely (hangs) and becomes unresponsive
  • ⚠Task Manager shows the application as 'Not Responding'
  • ⚠CPU usage drops to near zero for the hung application
  • ⚠Application must be force-closed via Task Manager

DIY Fix

Beginner-friendly steps you can try at home

  1. 1Wait a few minutes — the application may eventually recover if it is a timeout issue
  2. 2Force-close the application via Task Manager and restart it
  3. 3Update the application to the latest version
  4. 4If it happens when accessing a file on a network, check network connectivity

Advanced Fix

For experienced users and IT professionals

  1. 1Use WinDbg to attach to the hung process and run !locks to see held locks
  2. 2Use Process Explorer to view thread stacks and identify which threads are waiting
  3. 3Enable lock-order checking in Application Verifier for development
  4. 4Capture a hang dump using procdump -ma -h <process> and analyze offline
  5. 5Review wait chain: Task Manager > Details tab > right-click process > Analyze wait chain

Frequently Asked Questions

What is a deadlock?
A deadlock occurs when two or more threads each hold a resource and wait for the other to release theirs. Since neither can proceed, the application freezes indefinitely. For example, Thread A holds Lock 1 and waits for Lock 2, while Thread B holds Lock 2 and waits for Lock 1.
How can I tell if my application is deadlocked vs just slow?
Check the CPU usage of the process in Task Manager. A deadlocked application typically shows 0% CPU because all threads are waiting. A slow application will still show some CPU activity. You can also use the 'Analyze wait chain' feature in Task Manager.
