Is this visible to the clients? I.e. does it cause any actual problem like incomplete responses? > Program terminated with signal 11, Segmentation fault. > #0 Perl_csighandler (sig=15, sip=<value optimized out>, uap=<value optimized > out>) at mg.c:1372 > #1 <signal handler called> > #2 0x00007f9ec27613e4 in do_lookup_x (new_hash=1842243024, > old_hash=0x7fffc4fe0508, ref=<value optimized out>, > result=<value optimized out>, scope=<value optimized out>, i=5, flags=1, > skip=0x0, undef_map=0x2215b50) at dl-lookup.c:241 > #3 0x00007f9ec27617e2 in _dl_lookup_symbol_x (undef_name=<value optimized > out>, undef_map=0x2215b50, ref=0x7fffc4fe0568, > symbol_scope=<value optimized out>, version=0x2200468, type_class=<value > optimized out>, flags=1, skip_map=0x0) at dl-lookup.c:721 > #4 0x00007f9ec2765352 in _dl_fixup (l=<value optimized out>, > reloc_arg=<value optimized out>) at ../elf/dl-runtime.c:118 > #5 0x00007f9ec276b395 in _dl_runtime_resolve () at > ../sysdeps/x86_64/dl-trampoline.S:41 > #6 0x00007f9ebf021d86 in ??

() This might be the 'crash without threads' case in http://rt.perl.org/rt3/Public/Bug/Display.html?id=60724 in which case change http://perl5.git.perl.org/perl.git/commit/01be0729981136a058cce07a897ccdb94609e1c0 would fix it. I can imagine this happening if Apache kills its CGI children with SIGTERM (sig=15 above) for some reason and the script happens to be simultaneously exiting itself. The above change is in Perl 5.12, wich will enter Debian after the Squeeze release. It's rather hard to be certain if this is the right fix. Markus, if this is reproducible enough for you would you like to test if the fix works? You could rebuild the perl package yourself with the patch (it applies cleanly against 5.10.1), or I can provide you the .debs if you like. -- Niko Tyni nt...@debian.org -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
