    Hi.
    First of all I'm not sure this is directly related to ISPConfig.
    I noticed a 500 Internal Error on a website with medium traffic ~50k per week.
    After connected via FTP and there were around 10000 autogenerated(?) files in main web named like that:
    The early ones was 500mb each and around the end 0bytes(probably because the disk was full).

    I deleted the files(some of them are saved locally and they seem binary files) and reboot the server.
    I also checked the virtuozzo server resources and there is up-normally high CPU load. Some times over 80% sometimes under 15%.

    After that I run chkrootkit and rkhunter with no primary warnings.
    chkrootkit reported nothing found except:
    and rkhunter reported no worms or rootkits but those warnings

    Its is a VPS server and the service company said that the haven't changed anything(but they have claimed that before and wasn't true)...
    The last version of ISPConfig is installed and I update Debian Jessie every 15 days.


    Any help is appreciated...
