Hello Team, After lessons learned on clamav being RAM hungry the best I could do with the budget provided was to increase the swap so the server now has 2GB RAM and 4 GB swap (before was 2+2). So now the server is running with 2+4 GB of RAM but I see surge in CPU usage and looking at htop it's clamscan: Code: Uptime: 01:02:50 PID USER PRI NI VIRT RES SHR S CPU% MEM% TIME+ Command 23277 amavis 20 0 848M 475M 932 R 15.2 24.1 0:57.60 /usr/bin/clamscan --stdout --no-summary -r --tempdir=/var/lib/amavis/tmp /var/lib/amavis/tmp/amavis-20191013T191629-01876-1HU_EX2v/parts 23381 amavis 20 0 375M 286M 608 R 69.7 14.5 0:15.21 /usr/bin/clamscan --stdout --no-summary -r --tempdir=/var/lib/amavis/tmp /var/lib/amavis/tmp/amavis-20191013T191803-01877-IKHIsAjj/parts Since the server was before clearly RAM&swap exhausted and eventually probably even gave up on checking (emails started to come in as ***UNCHECKED***) I did shutdown, increased the SWAP and now nail biting watching the CPU usage spike. What is the default configuration (or behavior) of clamav? Does it now try to catch up scanning on the previously unscanned emails or what is going on? Is there any way to check the progress of the clamscan and to see what is it actually doing? Thank you all very much in advance.
