 04 Nov 2008, Suannah Daviel, Bug Report, bool values in "/custom/images/my_image.gif/labels/src" seem to lose their format string

Not sure if this is a bug or a feature:
Writing a boolean label on an image seems to produce rather strange behaviour.

computing center) and after rebooting ladd00, https/ssl access stopped working with a complaint
about mismatching server name and ssl certificate name. This configuration used to work, so one of the

23 Oct 2008, Konstantin Olchanski, Bug Report, strange output from "odbedit cleanup"
|
When I run odbedit remotely (odbedit -h ladd09), the "cleanup" command unexpectedly produces the
output of the "sor" command (sure enough, there is a call to db_get_open_records() there), but when I run
it locally, I do not get this output (but db_get_open_records() is still called). Strange. K.O. |

23 Oct 2008, Konstantin Olchanski, Bug Report, Inconsistent handling of odb and evet buffer timeouts
|
In midas.c there are several places where client last activity time stamps are checked against the
watchdog timeout and the clients are declared dead if they fail to update their activity time stamps.
ODB time stamps and data buffer time stamps appear to be handled in a similar manner.

When mserver receives events from remote client, writes them into a data buffer and this data buffer
becomes 100% full, we see mserver go into 100% consumption.
