I'm using puppetmaster with mongrel/apache.
I had a syntax error in a manifest and got this error:
err: Could not retrieve catalog from remote server: Error 502 on SERVER: Proxy Error
Further, when I fixed the syntax error, it doesn't always work first run, eg:
Syntax OK:
[root@a001 puppet]# puppetd --test info: Caching catalog for a001.private.statcounter.com info: Applying configuration version '1249597134' notice: Finished catalog run in 1.12 seconds
Introduce an error:
[root@a001 puppet]# vi /etc/puppet/modules/core/manifests/firewall.pp [root@a001 puppet]# puppetd --test err: Could not retrieve catalog from remote server: Error 502 on SERVER: Proxy Error notice: Using cached catalog info: Applying configuration version '1249597134' notice: Finished catalog run in 1.15 seconds
Fix the error and retry. Notice the configuration version is the old one for the first two tries.

Hi Robin - what was the syntax error?

The original one was using "if $foo = 'bar'" instead of "if $foo == 'bar'"
However, I simulated the same error by just typing "zzz" as the first line of the class. Or was it "xxx" - I forget ;)

Can you provide your apache error log, just to see what kind of error it reports?

Brice,
I'm afraid I've had to drop back to 0.24.8 as I was having too many problems with 0.25 and I needed to deliver something.
I may move to 0.25 at some stage in the near future, but I'm sticking with 0.24.8 for now.
R.

Anyone have a simple mongrel setup in place they can use to test this?
It works fine with webrick, ftr.

I believe there are two things going on here:
- That the delay between the syntax error being fixed and the modified file being picked up (due to the normal file cache time out) is confusing the issue by making it appear that the error "hangs around" briefly after having been fixed; this is simply normal latency.
- That some configuration issue with the proxy is causing the error to be reported in a less than useful fashion.
From the information provided I've not been able to diagnose it further, nor have I been able to reproduce it.

Without any more information I'm going to close to bump this if it can't be reproduced. Robin?

I'm unlikely to get change to test 0.25 again in the near future so go ahead and close. I'll re-open/raise a new bug if/when I see the same thing again.

I just ran across this on 0.25.4 due to a syntax error in a template file. I had failed to terminate a tag on an if statement. Luckily this bug existed, but looks like it has never been fixed. I should be able to reproduce this easily in a test environment.
