In the middle of some fairly heavy Coda activity I got an assertion failure
from venus. I'm running this on a 2.0.35 kernel Linux box (so it could be
my fault ... :-).

Anyway, in the hope that this is of some use to someone -

/usr/coda/etc/console says

RVMLIB_ASSERT: error in rvmlib_malloc

Assertion failed: 0, file "/usr/src/redhat/BUILD/coda-5.2.3/coda-src/util/rvmlib.c", line 217
Sleeping forever.  You may use gdb to attach to process 33.

And gdb says
