Expected Behavior

No panic

Current Behavior

Panic

Possible Solution

Do not do out of range?

Steps to Reproduce (for bugs)

Not sure, some high load with blocks that @AnnaShaleva and @AliceInHunterland usually do.

Context

Loading neo-go blocks to NeoFS.

Your Environment

NeoFS Storage node Version: 0.43.0 GoVersion: go1.22.6

It always had util/log.go:19 could not push task to worker pool {"request": "PUT", "error": "too many goroutines blocked on submit or Nonblocking is set"} log before panic.

1. We have a lot (thousands) of these on all machines.
2. Happens during load.
3. Not related to network map changes.
4. Offset is always 109:0.
5. Tends to come in series of 3-5 events at sub-second level on a single machine.

@roman-khimov, i think we found the root reason for it? Also we know that it will not be possible in 0.44

[roman-khimov]

It will be possible if you won't fix it. master can still have this problem.
