Before creating this thread, i have googled and found some threads on litespeedtech, but i still can't fix it. So i have to create a thread. I use : Litespeed Web Server Enterprise v4.1.12 (2 cpu license) I have APC installed. On last few days, i have stability issue on the webserver. I think it is restarted because i have apc script that detects the APC uptime. I think APC uptime relates closely with litespeed uptime so i check the litespeed log, i find quite lot of this line : Code: [[B][color=red]220.127.116.11[/color][/B]:2285-0#APVH_mydomain.com] connection to [/tmp/lshttpd/lsphp5.sock.153] on request #100, confirmed, 0, associated process: 18119, running: 1, error: Connection reset by peer! Before that line, i only find lot of 404 not found lines. And i've tried to search IP address (18.104.22.168 on the example above) on the litespeed log several pages before that line, but i see no matching IP. Please help me to find out whether that "Connection reset by peer" relates to my server uptime. And if so, how to fix it. Thanks.
