I am really tired of 503 errors. I have setup a new apache server and transferring some of my websites to apache. I have tried all versions, including 4.1.0RC1 and compiled php several times (5.2.8, 5.2.9, 5.2.10) but no luck. What is the exact cause of this problem and how can I fix? I have two servers with this problem and I am in a very big trouble...
Thanks in advance...

Is it random or consistent with certain request.
If it is consistent, it must be a problem with your PHP.
Also, you should disable opcode cache during the trouble shooting.

I am sorry but my experiences are same about 503 errors. It is rondom, sometimes people get 503 error, somtimes blank pages. Is there a link to download older versions like 4.0.4? There was no problem with this version.

BTW I really want to undersand the reason. For example what causes to "Max retries has been reached, 503!". May be there can is a configuration issue. I really need urgent help...

Click to expand...
just change the version number in the download URL. for example, latest one is
.../4.0/lsws-4.0.10-ent-i386-linux.tar.gz
change to
.../4.0/lsws-4.0.4-ent-i386-linux.tar.gz

can have a try and see if any difference.

if GUI upgrade/downgrade fail, may need run command line as root:
cd /path/to/lsws-4.0.4/
./install.sh

update: sorry, looks like 4.0.4 not there where 4.0.6/4.0.9 still exists. if you ever downloaded 4.0.4, it may still exist somewhere on your server. for example /usr/local/lsws/...

Yes I have tried that but iy gives 404. I think older versions are deleted from download repo. I have completely deleted whole lsws directory and made a fresh install but no luck. I have randomized 503 pages...

You can get 4.0.6 which is stable.
If you want to switch between 4.0.10 and other version, you need to run the installer and do a manual upgrade.

That's because the admin console uses suEXEC in 4.0.10 release.
