I suspect this is related to the increase in executors.  I'll schedule Hudson for a restart, but that's a temporary fix.  

-M.

Comment 2 Matt Heitz 2012-02-09 11:54:59 EST

It's working again.  Thanks.

Comment 3 Matt Heitz 2012-02-10 09:14:32 EST

The same error at https://hudson.eclipse.org/hudson/job/dltk-nightly/100/console

Comment 6 Eclipse Webmaster 2012-06-06 10:03:47 EDT

I'll have to re-start the slave, but it's pretty busy.

-M.

Comment 7 Eclipse Webmaster 2012-06-06 14:13:10 EDT

I've restarted slave1, let me know if the issue persists.

-M.

Comment 8 Alex Panchenko 2012-06-06 15:40:12 EDT

It still doesn't work.
