comment 1 posting successful via wsm0 account.
whereas, posting via vseerror account fails

Comment 3

aj concludes my posting problem is somehow related to my vseerror BMO account.  Which is odd, because I use my account many times since the BMO 4.2.5 update ... no problems until 4:30pm EST today, Sunday

for grins, I granted wsm0 editbugs and canconfirm priveleges and I was just able to post the changes. So, my problem with vseerror account is not strictly related to having those priveleges.

i suspect one of the webheads was having transient problems, resulting in the errors you're seeing.  i don't think it's related to your [e-mail] account.

there have been memory consumption issues reported across the webheads, which we're tracking down, so it's possible you've been hitting this.

i'll do some more investigation and report back if i find anything of interest.

Hello.

I've been trying to vote for a few bugs since March 10th 11:30 PST and I always get either "Service Unavailable" or "Internal Server Error". I'm logged in via my regular Bugzilla account, not Persona.

Now that I am able to comment, here is a copy of some of my emails:
* April 5th:
"When I try to save changes on comments, crash signatures or file a new bug, I get Service Unavailable at least up to 8H UTC the next day. Editing only tracking flags or keywords seems OK.
It seems to show up again when I change many bugs in a row.
It started showing up at the end of April 3rd."

* April 5th:
"I added a comment in https://bugzilla.mozilla.org/show_bug.cgi?id=786153 and get Service Unavailable at 13:00:30 UTC
I added a crash signature in https://bugzilla.mozilla.org/show_bug.cgi?id=848913 and get Service Unavailable at 13:02:25 UTC
I submitted a new bug and get Service Unavailable at 13:04:08 UTC"

* April 6th:
"It was back to normal around 17H UTC.
I think I found the culprit, https://bugzilla.mozilla.org/show_bug.cgi?id=848913, because after having added a crash signature to it a few minutes ago, I got again Service Unavailable for all bugs I comment or add a crash signature. I now remember that it started this morning and yesterday evening with the same operation."

[:glob ✱]

an errant setting on bugzilla.mozilla.org's load balancer appears to have been the cause of the "service unavailable" errors.  this setting has been changed, so we should be good now.
