[solved] Usually showing "cannot display the web page"

[redstrike]

Hello,

I am using LiteSpeed 4.1.4. I usually got the "cannot display the web page" after a few hit to navigate, in front-end, back-end, phpmyadmin too.

I don't know why. But server is running normally, not disk i/o, not high load, in very fast state. Although, it returns error page the database is working and update my queries.

anything in the error log (e.g. /usr/local/lsws/logs/error.log)? what platform (OS version, etc) in question?

Nothing special in error.log, I am using CentOS 5.6

It's seem that problems happen in peak hours. My VPS remains a lot of RAM, CPU not high load, no disk I/O.

I have found that top shows %CPU of litespeed instane is > 99% for a coupe of seconds.

What is the problem in this case?

I can add that on my machine all wordpress sites give 403 errors whenever you edit a post and add ANY html valid element in them (i.e. <br> or <b></b>). It will error out on 403 upon save.

I had to roll back to 4.1.3 to solve it.
There seems to be some bug in 4.1.4 around parsing.

I have already posted 4.1.4 ugrade resulted in 406 errors which on 4.1.3 never happened. So i have downgraded to 4.1.3. Seems 4.1.4 has some issues.

On CentOS 5.x
cPanel/WHM.

Yeah. I hope they solve it soon.

please post more details of 406 error if any from error log (e.g. /usr/local/apache/logs/error_log).

However, here's more detail (not from logs):

4.1.3 works fine on all sites (commercial cms based).
When upgraded to 4.1.4 images being posted in body of article gives rise to 406 errors and the article gets saved without the image.

As a result of this had to downgrade to 4.1.3 where everything works fine.
Pl note that there's no change in any configuration done on server (except for upgrade to 4.1.4) so there's no other variable which could be causing this as only change that happens is Upgrade to 4.1.4 from 4.1.3

Currently running 4.1.3 (downgraded from 4.1.4) with no such error.

Regards

Any one can reliably reproduce this problem with 4.1.4, please contact bug@litespeed..., we need to figure out what exactly causing this problem.
