Parcel reading exceptions after "too many open files" errors

[Revertron]

Issue Details

Investigation of events in sentry leads to an assumption that sometimes AdGuard maintains too many open connections, leading to different parcel reading (opening) errors.

Logs show multiple exceptions like "too many open files", and right after that uncaught exception occurs.

There was done some work on this, we added some descriptors counter and added pushing it (the descriptor maximum) to the limits. This issue will become very rare, if not disappear at all.
