 13:02:13 < phk> (Please add that info to ticket)
 13:02:16 < nan0r> me & lupi are the guys
 13:02:35 < phk> nan0r, cool, thanks for participating.
 13:03:18 < nan0r> phk: you are welcome
 13:03:21 < phk> nan0r, what's the regular traffic level ?  (Just to get an
 idea
                 of the frequency of lost references) ?
 13:03:23 < lochii> how do we track refcount increments / decrements
 13:03:32 < nan0r> us + lochii
 13:03:55 < phk> lochii, you shouldn't have to :-)
 13:04:13 < phk> lochii, so we don't have any logging for it.
 13:04:21 < lochii> so this is the vcl->busy counter?
 13:04:25 < phk> however, there may be varnishstat counters that spot this.
 13:04:32 < phk> lochii, yes.
 13:04:46 -!- hu_made_this_script [Adium at 87.253.171.197] has joined
           #varnish-hacking
 13:04:50 < nan0r> quite a lot of traffic, about 100 backends, 300 req/s,
                   sessions let me check
 13:05:11 < phk> so basically, whenever a worker is doing something, it
 holds a
                 ref on the VCL so that it can call the different methods
 in the
                 same VCL until the transaction is completed.
 13:05:38 < phk> are you using dynamic backends or only static backends ?
 13:06:02 < lochii> nan0r: ?
 13:06:04 < lochii> I think only static
 13:06:05 < nan0r> 50 connections / sec
 13:06:16 < phk> lochii, any directors at all ?
 13:06:18 < nan0r> phk: static backedns only
 13:06:42 < lochii> I dont think any directors
 13:06:44 < nan0r> all declared in main vcl, not in vmods
 13:06:50 < lochii> yes, no vmods
 13:06:58 < phk> cool, that eliminates a lot of variables.
