Resetting the Talos benchmark hurt me today, so it would be really painful for me to see the stuff that I've been working on try disappear by resetting try.  :(

I have noticed a push being slow today. I will time it next time I push something.
Last try was

real	1m45.594s
user	0m1.094s
sys	0m0.185s
now it is

real	2m58.934s

Ben, any thoughts from your hg archeology?

I haven't been looking at try as much as fixing the underlying problems with varnish, which appear to be completed now, so I can focus on this.

try pushes get sent from nginx on dm-hg02 directly to apache on dm-vcview04.  dm-vcview04 apache is extremely busy, pegging all 8 cores with a loadavg hovering around 20.  The load is entire CPU-bound, with very little iowait.  I'm wondering if the load itself could explain slow push times.

looks like it just got really bad:

remote: waiting for lock on repository /repo/hg/mozilla/try held by 'dm-svn02.mozilla.org:30578'
remote: abort: repository /repo/hg/mozilla/try: timed out waiting for lock held by dm-svn02.mozilla.org:30578
abort: unexpected response: empty string
Bug 708632 is a more recent incarnation of this.
