Trying to narrow down the cause, but figure this forum is the best place to start.
Running Multi-Site and using the stock CBox theme for the front page. P2 Theme for the subsites below.
I logged into the back end today to make sure all was well. Found WP 3.5.2 upgrade offered, along with some updates to plugins and the P2 theme.
I did the upgrade for WP first and was told I need to update all the sites, so I accepted this option and did so. All was evidently OK until an error popped up saying one of the subsites couldn’t be updated. I believe it suggested I didn’t have sufficient rights to that site, which is odd because my account has control over everything. No other obvious problems, so I did the theme and plugin updates before poking into the single subsite problem.
I then noted that the admin area was dog slow. But the public side of the site remains as snappy as it ever was.
No load is noted on the server during the delays. It looks very much like a DNS timeout problem, where the server has no additional load but simply does nothing until the DNS officially fails… if you know what I mean. No errors that I can find, but I honestly don’t know where besides the typical Apache logs I should be looking. The delay is very close to a minute exactly and the browser simply shows ‘waiting for server’ during the delay. Once the connection with the server is finally established, the page populates as quick as ever.
I found a posting elsewhere discussing a similar symptom and note that the problem was tracked back to a routine that was attempting to notify the admin user of a new theme version. I don’t know if that’s possibly a clue here or not.
Any suggestions as to where I should be looking? I’m tempted to disable CBox and look to see what updates become visible… thinking perhaps one didn’t complete but isn’t visible through the CBox update controls.
