Package: php5
Version: 5.2.6.dfsg.1-1+lenny2
Severity: normal
We have a web server providing shared hosting and using PHP5.
It was upgraded from Debian Sarge via Etch, to Lenny recently, at which point
it switched to using the
Debian stock PHP5 packages (from dotdeb).
Since the upgrade to Lenny /var/log/kern.log reports errors like these below:

The installation has a fair amount of history including 3rd party PHP5 packages
before lenny.
I'd anticpated that the upgrade to lenny would have cleared out most PHP5
issues, as all previously installed PHP5 packages were removed as part of the
upgrade procedure we followed, and then reinstalled. Although most
configuration data in /etc/php5 was preserved.
Similar bug report suggests stale libraries in /usr/local/lib/ can cause
segfaults - the only PHP related code in that folder is the ioncube loader,
which reports itself to be installed correctly, and works (i.e. ioncube encoded
files are decoded and executed as expected using v5.2 of the loader).
I've been unable to correlate the segfault errors in /var/log/kern.log with any
particular set of http requests, so I'm unsure
how to progress troubleshooting at this point since I don't have a reproducible
case (or a discernable problem!).
I've installed php5-dbg when troubleshooting this previously.
Since I can't correlate the error message with any specific fault, I've marked
the bug as minor. However I appreciate that segfaulting in php5 may reflect a
more serious underlying bug (or misconfiguration).
Various troubleshooting guides suggest removing modules from php configuration,
and seeing if the issue is corrected, but without a test case this would
require running the server without major functionality for extended periods
which isn't acceptable.
I have an (almost) identically configured server that produced the same errors
(when it was live) which can be made accessible to trusted parties (i.e.
Package maintainers or relevant DDs), although obviously it doesn't receive any
traffic, and the error doesn't occur routinely when the server is idle.
