[clamav-users] clamav-daemon crashing periodically

[Jesús Arnáiz]

Hi,

Thanks for your kind message.

Indeed it looks as an issue related to RAM. Reading Freshclam logs all 
issues came exactly at that moment when a new DB started to be processed.

Very well explained.

*** I sent this message days ago, but I used the wrong account and it 
was returned recently, sorry if I was not quicker with the feedback.

Best Regards,
Jesús.
