Zabbix-proxy перестает слать данные.

[Cramac]

Всем привет. Недавно начал прокси мудрить, не шлет данные на сервер.
По логам ничего подозрительного. Были ошибки на заполненный кэш, увеличил, ошибка ушла но данные так и тормозяться.

При этом процесс заббикс прокси виснет намертво, помогает только kill -9 , после рестарта, все нормально какое то время.
