Are you running an HDD or SSD? If it's an HDD and the write throughput
is low that blocks are not being indexed/written fast enough, then the
memory buffer is filling up as new blocks are queued in the database.

The only way to resolve that (if it's the problem) is by a) making pure
writes faster or b) indexing less data (not a fan of this) [note: not
pruning but just not indexing].

------------

Can you update from the Git repo, and enable this new switch in your
config file:

https://github.com/spesmilo/obelisk/blob/master/src/worker/worker.cfg#L32

log_requests = true

Clear your log files, then run the daemon.

$ grep request debug.log

will give you some idea of the requests being run on the daemon.
