Litespeed Seems to Restart Alot

[dlewis23]

I'm having a somewhat annoying issue were litespeed seems to restart often. Usually the up time on the Real-Time Stats is no higher then an hour and 20 minutes or so.

This is kind of an annoying problem since I run a high end file host and people can be downloading files as large as 2 GB and that could be interrupted if Litespeed is restarting often.

Is there anything I can look into or change to stop this?

Thanks

adjust "Graceful Restart Timeout (secs)"
Server->General->Graceful Restart Timeout (secs):-1

"During graceful restart, the new server instance is up, while the old instance will continue to handle existing requests. This timeout defines how long the previous instance shall wait before exit. Default value is 300 seconds, -1 means wait forever, 0 means no wait and abort immediately."

Thanks for your reply. I set that to -1 and it still seems to restart about every hour or so. Is there any other settings I should look into?

Thanks

need check the error.log(or error_log) and/or stderr.log why it restart every hour.

if your website only serve static content, it's not likely to restart often. I managed a few high traffic websites, one is images only, another one has simple php, both of them don't restart for months/weeks, usually restart when I upgrade lsws version or do some configuration changes.

Most of what is being served is dynamic PHP content. From images to large file downloads its all done through PHP.

I will check the error.log right after it restarts next.

I was able to catch it right when it restarted, but there doesn't seem to be much in the error_log log. It just says when it restarted.

Here is a few lines before and after.

can you explain more about large file download through php?
if it's possible, try serve large static file through "X-LiteSpeed-Location

that will improve the overall performance, reduce the memory usage of php a lot.

I guess this issue is related to memory usage of php.

also you can try 4.1RC4 to see if any difference.
