Hi Forks, I have an application that reported high (more than 1 second) times to process *zero* SoftReferences, for example:
2020-08-11T18:58:19.222+0800: 611331.604: [SoftReference, 0 refs, 1.4741673 secs]2020-08-11T18:58:20.696+0800: 611333.079: [WeakReference, 0 refs, 0.0004746 secs]2020-08-11T18:58:20.696+0800: 611333.079: [FinalReference, 4559 refs, 0.0019431 secs]2020-08-11T18:58:20.698+0800: 611333.081: [PhantomReference, 2 refs, 0 refs, 0.0016303 secs]2020-08-11T18:58:20.700+0800: 611333.083: [JNI Weak Reference, 0.0000284 secs], 1.4867549 secs] 2020-08-14T02:58:22.222+0800: 812934.605: [SoftReference, 0 refs, 1.0247147 secs]2020-08-14T02:58:23.247+0800: 812935.629: [WeakReference, 1 refs, 0.0007859 secs]2020-08-14T02:58:23.247+0800: 812935.630: [FinalReference, 4382 refs, 0.0024934 secs]2020-08-14T02:58:23.250+0800: 812935.633: [PhantomReference, 2 refs, 0 refs, 0.0008613 secs]2020-08-14T02:58:23.251+0800: 812935.634: [JNI Weak Reference, 0.0000239 secs], 1.0380333 secs] We have been hit by this anomaly a few times now, and detailed information can be find in the attached logs (that also show the command line flags).
