I've been hitting this every time I do 'emerge --sync' lately. Emerge copies all the files, then goes into the updating portage cache section. When it gets to 53%, my computer nearly instantly uses all of its memory and starts doing tons of paging. A few minutes later, emerge crashes. Below are the relevant lines from the output. sent 100579 bytes received 8692819 bytes 81045.14 bytes/sec total size is 167707932 speedup is 19.07 >>> Updating Portage cache: 53%Traceback (most recent call last): File "/usr/bin/emerge", line 5676, in ? retval = emerge_main() File "/usr/bin/emerge", line 5631, in emerge_main action_sync(settings, trees, mtimedb, myopts, myaction) File "/usr/bin/emerge", line 4336, in action_sync action_metadata(settings, portdb, myopts) File "/usr/bin/emerge", line 4430, in action_metadata eclass_cache=ec, verbose_instance=noise_maker) File "/usr/lib/portage/pym/cache/util.py", line 41, in mirror_cache trg = trg_cache[x] File "/usr/lib64/portage/pym/cache/flat_hash.py", line 28, in __getitem__ d = self._parse_data(myf, cpv) File "/usr/lib64/portage/pym/cache/flat_hash.py", line 43, in _parse_data d = dict(map(lambda x:x.rstrip("\n").split("=", 1), data)) MemoryError Reproducible: Always Steps to Reproduce: 1. emerge --sync Actual Results: emerge crashes, giving the traceback in the Description field.

Looks like filesystem corruption. Here is a workaround: rm -rf /var/cache/edb/dep && emerge --metadata *** This bug has been marked as a duplicate of bug 179549 ***
Thanks, that fixed the problem. Sorry I wasn't able to find it with a simple Google search.
