New issue 301 by gm130s: rtcd increases too many
http://code.google.com/p/rtm-ros-robotics/issues/detail?id=301



With new robot we're imstalling, we're seeing bizarre behavior of rtcd; we
haven't yet determined how to replicate the issue but we feel:

- #rtcd remains 13 or so when connecting and dicconnecting to robot
- After awhile, #rtcd suddenly jumps up. 20 in the example below

Comment #1 on issue 301 by kei.ok...@gmail.com: rtcd increases too many

It seems that #rtcd indicates the number of threads in rtcd process
If so, it might related to the connection type.

Users are able to select connection type ( subscription type ) from new or
flush. If user choose one of them, the rtm process create one thread for
data transmission.

If you observe the #rtcd and that continuously increases, that would be
strange. But if it increases for initial status, that would be ok.

yes, the number of rtcd.

We found today the number is so unpredictable; sometimes goes up
immediately after rebooting rtcd, sometimes do so only after awhile. We'll
keep watching tomorrow as much as time allows.

So we watched over for almost a day and couldn't find anything that causes
this issue. We didn't see either the #rtcd jumped up to more than 30, which
we can't even tell if it's bad or negligible.
