There was another report of a crash in that part of the code a few
weeks ago. Was your cache partition full?
Yes, very possible.
analysis and possible fixes:
The comment above this block says:
/* now, if code != 0, we have an error and should punt.
* note that we have the vcache write lock, either because
* !setLocks or slowPass.
*/
if (code) {
it turns out that this is not the case for a dynroot vcache, since the
dynroot codepath does not retry with slowPass=1 on error conditions. I
have two proposed possible fixes for this. One runs dynroot fetches
with slowPass=1, since they don't have to wait for network I/O (and so
won't be holding the write lock across a "slow" network operation).
The other assumes that dynroot vcaches don't need all the same
callback processing as normal vcaches and can get away with not
getting a write lock in the error case.
Ok. I applied fix #1 as a temporary fix. Thanks for the quick help.
