clamav/freshclam-sleep
ensc 21bb824baf Fixed calculation of sleep duration; on some systems/IPs, hostid results
in a negative number which is retained by the bash modulo-operation. So
    the sleep may get a negative number of seconds being interpreted as an
    option. This version makes sure that the module-operations returns a
    non-negative value. [BZ #164494, James Wilkinson]
