Description

I cannot always reproduce this, but this happens in my concurrent test code and my business code is using MemoryLockFactory from EasyCaching.Core.

System.ObjectDisposedException: Cannot access a disposed object.
  Object name: 'System.Threading.SemaphoreSlim'.
     at System.Threading.SemaphoreSlim.WaitAsync(Int32 millisecondsTimeout, CancellationToken cancellationToken)
     at EasyCaching.Core.DistributedLock.MemoryLock.LockAsync(Int32 millisecondsTimeout, CancellationToken cancellationToken)

}
finally {
    await distributedLock.ReleaseAsync();
}
