The query is in the backtrace:
SELECT PATH, COUNT(SITE_ID)
FROM ACCESS_LOG_05
WHERE SITE_ID = $1
GROUP BY PATH
ORDER BY PATH
And it also suggests that the crash is happening during cache lookup of
the "count" function.
Since this seems to work for pretty much everybody, I would wonder about
corrupt catalogs and/or corrupt cache; if neither, perhaps some race
condition on cache invalidation/reload. Speculating much without any
further evidence or test case appears pointless.
