4.0.5 very unstable - restarted automatically 503 error

[piper]

I have 4 servers running 4.0.5 hosting 1-2 large wordpress blog/machine

We never have problem with 4.0.4 and previous releases but 4.0.5 has been restarting itself due to 503 frequently.

Any idea what causes it? all of them runs standard installation of wordpress.

It happens to all 4 server (1 which hosts a single activecollab app)

After a little digging and troubleshooting, it appears to happen when i compile php 5.2.10 with --enable-bcmath, now all servers are happy

I guesss I was wrong, still gets 503, I'm going to stick with 4.0.4 for now, seems to work quite well

Can you send some piece of error log containing 503 errors to bug@lite....

sent, thx!

checked the server and the conclusion is that PHP 5.2.10 is not stable, give random crash causes 503 errors.


LSWS 4.0.5 + PHP 5.2.9 is super reliable and no 503 error at all. So, be cautious upgrading to PHP 5.2.10.

I've used the 3.x and 4.x versions with php 4 and never had an issue with server restarting due to 503 errors.

How to downgrade PHP from 5.2.10 to 5.2.9? just recompile PHP ?

Yes, just recompile it.
