Hi,

Has anyone noticed a bug when running syscheck with large files (> 2 GB)?

I created a test file of 750 MB and ran syscheck.  The file was added
correctly to the syscheck DB in /var/ossec/queue/syscheck/syscheck

+++755439186:33184:0:0:547ce19e677e67506bbf9ef7b4c6f42f:6036d5f6813b59fd1b461a59184b0e8ffb26a11b
!1334071299 /var/log/remote/large-file.log

I then appended logs to the file to create a 3GB file
-rw-r----- 1 root root 3021794472 Apr 10 11:35 large-file.log

I ran syscheck again and then noticed a weird alert

** Alert 1334072743.333516: mail  - ossec,syscheck,
2012 Apr 10 11:45:43 cbvmalv01->syscheck
Rule: 553 (level 7) -> 'File deleted. Unable to retrieve checksum.'
Src IP: (none)
User: (none)
File '/var/log/remote/large-file.log' was deleted. Unable to retrieve
checksum.

The file has not been deleted and is still present in the directory.

Additionally, I see that the syscheck DB shows the file as deleted, but
with a new entry showing the same file with 1 change.

!1334072743 /var/log/remote/large-file.log

Also, the file size is wrong (1273172824 instead of 3021794472)

Has anyone else noticed this?  Is there a workaround or a fix?

Regards,
Chris
