nginx-0.5.32 crashed

[Denis Erygin]

Собран с самописным простым модулем фильтром (draft),
который использует ngx_pcalloc для строк и буферов,
но память явно не чистит, оставляет это пулу nginx.

Корки очень редкие, ссылок на код модуля в них нет,
пока без понятия куда копать...

Это стандартный nginx без дополнительных модулей ?
