I tend to keep a Developer Console open when testing code, so that I can get debug logs automatically for my session. Today I am finding that when I open the console I do see logs appear, but after a while I stop getting them. It's not long enough for the console session to have timed out (maybe 10 minutes, sometimes less), and the Debug menu does not give the "Resume Updates" option. This is even happening when running anonymous apex code; after a few executions, it stops showing the logs. Closing and re-opening will start it capturing logs again.
I just realized that this sandbox was upgraded to Summer '15 this past weekend. Is anyone else having issues with logs being listed in the Developer Console?
edit: To be clear, I can click on a listed log and see it without issue. The issue is that after a brief interval, new logs stop appearing in the log panel.

I have also been experiencing this. Here are the steps that I have taken to 'fix it' quotes are because the fix seems to expire... sigh!
In the dev console debug ==> change log levels set the monitoring level on the classes you want to track in the log and set the expiration time to be in the future. The red ones are expiring so you want them to be green.
Also in the dev console, uncheck show my current logs only.
Through the Salesforce UI add yourself to the monitored users. Also in the SF UI under develop==> test execution ==> options uncheck store only aggregated code coverage.
These steps got me close to being able to monitor the logs as before... Good luck!
