"pretty obvious" as in "completely explains"? So, you are experiencing the same behaviour? Or, at least, know of someone else that has, ever? http://www.catb.org/~esr/faqs/smart-questions.html#id306810 > When it dies, there is a core file left behind; Is there? Well, there might be, and looking at the stack trace might even be a good idea (though you almost definitely will *not* find out ... > what part of backuppc_dump you were in to cause it ... because you'll see a C backtrace - probably of stripped code -, not a Perl backtrace, and Perl code cannot "cause" a SEGV anyway, only a bug in Perl or a module (part) implemented in C can). Do that if you like, but it is certainly not mandatory. I'd either try replacing libz.so.1.2.3.3 with an uncorrupted copy (check the md5sum of that file if you can; it may not, in fact, be a corrupted libz, but that's where I'd start looking), if the SEGV happens roughly at the same place each time, or else think about the possibility of hardware issues (memory, CPU, I/O, PSU, ...; are you observing any other unexplained problems?). I wouldn't go so far as to say any of that was obvious, let alone the only possible explanation. Hope that helps. Regards, Holger P.S.: I wouldn't discount running out of memory as a possible cause for a SEGV. It was a good idea to check that. ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
