Bug#352955: apt runs out of memory
Package: apt
Version: 0.6.43.2
Severity: normal
I'm running Xen so this is probably a Xen bug but it's still really
strange. apt fails to mmap because of running out of memory. I am
attaching the strace & /proc/meminfo. Can you confirm this is a Xen
bug? I tried apt 0.5.23 with approx the same results.
strace env -i apt-cache gencache
access("/var/cache/apt/", W_OK) = 0
stat64("/var/cache/apt/pkgcache.bin", 0xbffff8dc) = -1 ENOENT (No such
file or directory)
unlink("/var/cache/apt/pkgcache.bin") = -1 ENOENT (No such file or
directory)
lstat64("/var/cache/apt/pkgcache.bin", 0xbffff98c) = -1 ENOENT (No such
file or directory)

ftruncate(3, 0) = 0
close(3) = 0

write(2, "Couldn\'t make mmap of 12582912 b"..., 71Couldn't make mmap of
