Script takes about 5 minutes to run (average). On other servers I've
seen it run over 2 hours without segfaults... All depends on how many
messages are in the NNTP mailboxes.
After applying the mentioned patch to libc-client2002edebian the issue
persisted. No change...
I'm not running xdebug. The PHP memory limit is 512 Mb and server has
16Gb of RAM, so it doesn't look like its exhausting all the memory,
although one of the libraries potentially could?
If this helps: It looks like the script is dropping connection to the
NNTP server. If it then tries to open another mailbox, it segfaults.
Otherwise it continues to run successfully. But why does it drop the
connection?
Thanks a lot for your help!!

Everything matches. The only thing that's different is that the server

if the script isnt long running, *theorectically* speaking once php shuts
down, all php allocated memory should get freed up, unless theres a bigger
mem leak issue w/ php itself.
Although complete recompiling should reset something, right?
well if you were running an older version of php, and you upgraded to 5.2.8,
then theres a chance a mem leak bug could be fixed by it. but only if they
actually patched that problem. id be surprised to see a memory leak persist
after a php script has run to completion.
I found this:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=502996
But the patch didn't work. The library is required by php5-imap (which is a
standalone package).
hmm, so the extension wouldnt compile w/ the patch, or after building w/ the
patch the problem persists?
are you by chance running anything like xdebug on the server. that (and
similar extensions) keep a lot of things in memory during script execution
that php normally cleans up. once i had a cli script which would eat up all
of the memory on the box. even unset() calls wouldnt stop the madness.
then i realized i had xdebug running, disabled it, and bam, all was good
again.
also, do you have any idea, the duration of the script execution.
