Hi,
stepped into an infinite loop on freshclam when there's no permissions
for daily.inc and daily.inc/*.
I know the permissions are an install problem but it may happen and the
loop is a major CPU chewer:
root 232 0.0 0.0 1928 652 ? S 2006 0:46 /usr/sbin/cron
root 4915 0.0 0.0 2040 724 ? S 13:44 0:00 \_
/USR/SBIN/CRON
qscand 4916 73.9 0.0 2892 848 ? R 13:44 421:12 \_
/ptmail/av/bin/freshclam
root 4918 0.0 0.0 1524 300 ? S 13:44 0:00 \_
bin/qmail-inject -a -- root
qmailq 4922 0.0 0.0 1488 288 ? S 13:44 0:00 \_
bin/qmail-queue
Attached is a patch for shared/misc.c that fixes this (haven't tested
it though) and a strace dump of the looping process.
Best regards.
