Description Sir Raorn 2003-07-29 16:59:57 MSD 
Демон умирает по SIGXFSZ (File size limit exceeded) если один из его логфайлов разрастается до двух гигабайт (2147483647 байт). Файл открывается успешно, но попытка записи перерубается сигналом. После этого демон не стартует.

В случае когда файл больше 2G-1, open(2) возвращает EBIG и этот файл просто пропускается.

На файловой системе квот/ограничений нет (ext2/ext3, я лично создавал большие файлы). Кусок strace в Additional Information.

Comment 1 Dmitry V. Levin 2003-07-29 18:39:10 MSD 
Try to recompile with
%add_optflags -D_FILE_OFFSET_BITS=64
line added in %build section.

It should work but I have no platform for test ATM.

Comment 3 Sir Raorn 2003-07-30 11:22:48 MSD 
%add_optflags -D_FILE_OFFSET_BITS=64 works just fine.

Security update would be nice ;-)
