So you you must have written about 30000 files at that point. It doesn't
sound like that really should be much of a problem. How much RVM data
did you configure for this server? Even if every file would take about
2KB of RVM (don't really know the size, just a random approximation),
this should still take only 60MB.

Not really useful, RVM is a bit of a black box. This just tells me that
'allocation failed'. Don't know whether this was due to a problem with
the RVM log file, the RDS allocator, or some bug that corrupted memory.
If you apply the attached patch to coda-srv/util/rvmlib.c we can at
least get some info, the returned error code, how much we tried to
allocate and who tried to allocate.
