Try to fix `[futex_waiter.cc : 85] RAW: Futex operation failed with error -512`
Мы используем клиентскую либу unified agent'а. Она использует grpc, а он abseil. Похоже, что в ядре где-то баг, из-за которого syscall возвращает -512 (ERESTARTSYS) или -516 (ERESTART_RESTARTBLOCK), хотя должен EINTR.
Как обходной путь, лучше эти ошибки явно поретраить. После этого фикса у нас на сервисе пропадает фон корок
