On my error logs i see lot of lines like this 2013-11-29 07:19:58.096 [INFO] [220.127.116.11:37586-1#APVH_xxx.com] connection to [uds://tmp/lshttpd/lsphp5.sock.10266] on request #200, confirmed, 0, associated process: -1, running: 0, error: Broken pipe! 2013-11-29 07:20:18.619 [INFO] [18.104.22.168:53063-0#APVH_xxx.com] connection to [uds://tmp/lshttpd/lsphp5.sock.10266] on request #200, confirmed, 0, associated process: -1, running: 0, error: Connection reset by peer! Does that mean PHP is crashed? Even connecting by winscp & putty sometimes gives me timeout error, is it possible php crash affects SSH too? I've also read this other thread which seems related but i'm not sure http://www.litespeedtech.com/support/forum/showthread.php?t=3806 http://www.litespeedtech.com/support/forum/showthread.php?t=5777 I use : lsws 4.1.4 lsapi 6.6 PHP 5.3.27 External Application Abort : No abort Max Connections : 200 Run On Start Up: suexec daemon Max Idle Time : -1 Code: PHP_LSAPI_MAX_REQUESTS=200 PHP_LSAPI_CHILDREN=80 LSAPI_AVOID_FORK=1 LSAPI_ALLOW_CORE_DUMP=1 Should i increase the PHP_LSAPI_MAX_REQUESTS ? ------------ And i wonder where the lsapi core dump file is. For example if the troublesome php script is "/home/myuser/public_html/demo.php", the core dump will be on "/home/myuser/public_html/" ? What is the file name example of core dump file?
