These settings may be contributing to the problem. You should never run
the background writer that frequently--it just wastes resources and writes
more than it should. I'd suggest turning it off altogether
(bgwriter_lru_maxpages = 0) and seeing if things improve any, just to rule
that out as a potential source of issues.
