Additional info:

Comment 1 zhaozhanqi 2013-07-29 06:46:26 UTC

Tested on devenv_3573, it will show different errors:
[root@dhcp-10-143 openshift]# rhc threaddump zqruby19s
Error occured while processing event 'thread-dump':The rhc threaddump command is not supported on scaled gear: 51f60e5234393408ad000003. ssh into the gear and issue ~/ruby/bin/control threaddump.

Comment 2 Hiro Asari 2013-07-29 14:43:07 UTC

The latter result is correct; the Ruby cart does not support threaddump command on scaled applications.

It is not clear how it sneaked into the error originally reported, but if it doesn't happen now, please close this ticket.

Comment 3 zhaozhanqi 2013-07-30 03:29:30 UTC

Tested this on INT(devenv_3578),it is ok

dhcp-10-195:.openshift root# rhc threaddump zqruby18s
Error occured while processing event 'thread-dump':The rhc threaddump command is not supported on scaled gear: 51f602e003ef6499ee000002. ssh into the gear and issue ~/ruby/bin/control threaddump
