    how you use it so we can reproduce the problem in our lab If lshttpd crashed LSWS Enterprise users should switch to the debug build of lshttpd then submit the debug report generated and a core file if possible How to switch to the debug build of LSWS Enterprise For 4 x version there are two versions of the lshttpd binary shipped in the LSWS Enterprise package One is the release build The other is the debug build The debug build is not normally used when you run LSWS but when debugging the GDB stack backtrace and core file generated by the debug build are the most useful information you can provide for fixing the bug For latest version such as 5 0 x or 5 1 x the binary installed is debug info enabled by default hence no separate debug build version required It has no impact for your server performance How to download debug build of LSWS Enterprise For 4 x version if there is no debug build of lshttpd binary in your current installation you can download the related version and arch of debug build from our website For example usr local lsws admin misc lsup sh d f v your lsws version Once you have debug version installed reproduce your problem and submit a bug report For 5 0 x 5 1 x you do not need to switch to debug build anymore since the binary installed is debug info enabled by default It has no impact for your server performance How to enable a core dump For PHP By default core dumping is disabled in LSAPI PHP external applications To enable it you need to add an environment variable to your LSPHP external application configuration WebAdmin console Configuration External App your external application Environment LSAPI

    Tips The size of a dynamically generated page is limited by Max Dynamic Response Body Size bytes So if the block is too big the page might be truncated Real Time Statistics Description The Real Time Statistics link leads to a page with a real time server status report This is a convenient tool to monitor the system The report shows a snapshot of your server statistics The refresh rate for this snapshot is controlled by the Refresh Interval drop down list in the upper righthand corner The report contains the following sections Server Health shows the basic server statistics uptime load and anti DDoS blocked IPs Server lists current traffic throughput connections and requests statistics Virtual Host shows request processing statuses and external application statuses for each virtual host External Application lists the external applications currently running and their usage statistics The CGI daemon process lscgid is always running as an external application Many of the rows in the Real Time Statistics feature a graph icon Clicking on this icon will open a graph of that row s statistics updated in real time In the Server section next to Requests there is a link labeled Details This link takes you to the Requests Snapshot where you can view detailed information on which clients are making certain kinds of requests or which aspects of your site are bottlenecking The fields in the blue area allow you to filter the snapshot to isolate certain parts of your server or look for clients that are performing certain actions Toggle Debug Logging Description Toggle Debug Logging toggles the value of Debug Level between NONE and HIGH As debug logging has an impact on performance and can fill up the hard drive quickly so Debug Level should usually be set to NONE on a production server This feature can be used instead to turn debug logging on and off quickly in order to debug a problem on a production server Debug logging turned on or off in this way will not change anything shown in your server configurations Tips Toggle Debug Logging will only work if Log Level is set to DEBUG Performance Important Debug logging includes detailed information for each request and response Active debug logging will severely degrade service performance and potentially saturate disk space in a very short time This feature should only be used for a short period of time when trying to diagnose server issues See Also Debug Level Log Level Version Management Description Version Management found by clicking on the the version number at the top of the page is a convenient tool to manage LSWS versions It shows license info and information on all installed versions and available new releases If a new version has been released on the LiteSpeed website and Check For Update is enabled the new version will be listed with a Download link If Download Updates is enabled new versions will be automatically downloaded and the new version will be listed with an

    not contain symbolic link if symbolic links are not allowed By default LiteSpeed Web Server does not index a directory by listing its files it has to be enabled explicitly External application firewall LiteSpeed Web Server forwards requests to external applications to process generate dynamic content Those applications can use a lot of system resources The performance of the whole system will be severely degraded when system resource consumption reaches a certain point when swapping space has to be used for example One way to conduct a DoS attack is to flood the web server with concurrent requests to a cumbersome external application LiteSpeed Web Server can pipeline requests and control the concurrent level of external application use to prevent overconsumption of system resources LSWS caches requests and only forwards completed requests to the external application This means the external application will not be held waiting while the server is receiving the request LSWS also caches the external application s response so that the external application can be released as soon as the response is completed and does not have to wait for the client to receive the complete response This way the server can utilize fewer external application instances to serve more concurrent requests and achieve higher performance and scalability LiteSpeed Web Server also uses its own virtual memory to cache the request and response body to minimize the usage of system memory without sacrificing performance CGI resources consumption limit LiteSpeed Web Server restricts the amount of system resources that can be consumed by CGI applications For each request to a CGI script the web server needs to start a standalone CGI process to handle it On a Unix system the number of concurrent processes is limited With the CGI resources consumption limit you can configure the maximum number
