Hi All,

Our list server, running sympa 6.0.1, lost power yesterday and had to be 
fscked when it came back online. Since then, when we start sympa, the 
command sympa.pl process grows to using 12GB of memory and then dies.

We're a bit baffled, and I'm wondering if there is anything anyone can 
think of that would cause this, possibly related to hard drive or 
filesystem errors?

I managed to get an strace of the sympa.pl process before it dies, and 
this is what I see. I fear it's not very informative - it's not obvious 
to me what is eating the memory.

First there is a lot of this:

stat64("/home/sympa/bin/Template/Context.pmc", 0xbfde846c) = -1 ENOENT 
(No such file or directory)
stat64("/home/sympa/bin/Template/Context.pm", 0xbfde83e4) = -1 ENOENT 
(No such file or directory)
stat64("/usr/share/mhonarc/Template/Context.pmc", 0xbfde846c) = -1 
ENOENT (No such file or directory)
stat64("/usr/share/mhonarc/Template/Context.pm", 0xbfde83e4) = -1 ENOENT 
(No such file or directory)
stat64("/etc/perl/Template/Context.pmc", 0xbfde846c) = -1 ENOENT (No 
such file or directory)
stat64("/etc/perl/Template/Context.pm", 0xbfde83e4) = -1 ENOENT (No such 
file or directory)
stat64("/usr/local/lib/perl/5.10.0/Template/Context.pmc", 0xbfde846c) = 
-1 ENOENT (No such file or directory)
stat64("/usr/local/lib/perl/5.10.0/Template/Context.pm", 0xbfde83e4) = 
-1 ENOENT (No such file or directory)
stat64("/usr/local/share/perl/5.10.0/Template/Context.pmc", 0xbfde846c) 
= -1 ENOENT (No such file or directory)
stat64("/usr/local/share/perl/5.10.0/Template/Context.pm", 0xbfde83e4) = 
-1 ENOENT (No such file or directory)
stat64("/usr/lib/perl5/Template/Context.pmc", 0xbfde846c) = -1 ENOENT 
(No such file or directory)
stat64("/usr/lib/perl5/Template/Context.pm", {st_mode=S_IFREG|0644, 
st_size=54043, ...}) = 0
open("/usr/lib/perl5/Template/Context.pm", O_RDONLY|O_LARGEFILE) = 6
ioctl(6, SNDCTL_TMR_TIMEBASE or TCGETS, 0xbfde81f8) = -1 ENOTTY 
(Inappropriate ioctl for device)
_llseek(6, 0, [0], SEEK_CUR)            = 0

I am able to open the file /usr/lib/perl5/Template/Context.pm without a 
problem.

It does that loop for some time for various modules in the Template 
directory.

Then the last thing seen before the memory output is:

open("/usr/lib/perl5/Template/Iterator.pm", O_RDONLY|O_LARGEFILE) = 6
ioctl(6, SNDCTL_TMR_TIMEBASE or TCGETS, 0xbfde81f8) = -1 ENOTTY 
(Inappropriate ioctl for device)
_llseek(6, 0, [0], SEEK_CUR)
read(6, " $self->{ _DATA };\n    my $size ="..., 4096) = 4096
_llseek(6, 8104, [8104], SEEK_SET)      = 0
_llseek(6, 0, [8104], SEEK_CUR)         = 0
close(6)                                = 0
brk(0x2a7c0000)                         = 0x2a7c0000
mmap2(NULL, 327680, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 
0) = 0xb74a6000
mremap(0xb74a6000, 327680, 331776, MREMAP_MAYMOVE) = 0xb731c000

From there, it is mremap over and over again until it shows it's using 
12GB of memory, and then it dies with an out of memory error.

Thanks for any input!
