23.1 PHP recurring exceptions

[msmarcapo]

Hey,
after upgrade to 23.1.6 we got recurring exception reports on one of our nodes.
We automatically copy many of the config settings from one node to another via XMLRPC Sync.
How can we further analyse the root cause of this XML Error?
This behave started soon after upgrading to the new major version. Before we didn't get this problem.
Can we increase loglevel or anything to go ahead?

Thanks for your help!

It looks like the current /conf/config.xml may be damaged on that particular node throwing the error.

# xmllint --noout /conf/config.xml

(best to test all nodes with the command to be sure)


Cheers,

Thanks for Reply!
Unfortunately we can't get any further with this.
No Error shown.

How can we go ahead?

[franco]

I'm not sure. Either PHP or xmllint is lying or it wasn't the right test (location).


Cheers,
Franco
