We are seeing an issue where one-for-one increments in "sms_nreq/SMS allocator requests" are resulting in 503 errors. We are not getting any backend related errors. This is happening on a very small percentage of the page requests, but it is repeatable in our load-tests.
A couple questions: 1) Is this a problem that has been seen before? Is there a known configuration adjustment, work-around? 2) What specific function is performed by the SMS metrics measured in varnishstat? The most I've found in my digging is that it is used for internal memory house-keeping. There was a similar inquiry a couple of days ago on this message-list regarding SMS, SMA, SM, etc. It would be good if there was something published somewhere that elaborates on what these measure. _______________________________________________ varnish-misc mailing list [email protected] http://lists.varnish-cache.org/mailman/listinfo/varnish-misc
