Every now and then we received a large set of timeouts (around peak time for website traffic) with lots of logs in the following form:

What do sync-ops and conn-sec stand for? The rest of the numbers seem fine, but these seem high and I'm not entirely sure what they are describing.
These are statistic about the current connection:
"sync-ops" a count of synchronous operations (as opposed to async-ops for asynchronous operations) performed on the current connection.
"conn-sec" is the current duration of the current connection (from connected until now)
