Problem since upgrading to 4.2.0 from 4.1 - "data flooding from"

I've just upgraded my Hobbit server from 4.1 to 4.2 (on a Gentoo
2006.1 host), having had a need for "Disabled until OK" :)

The trouble that I now have is that reports from the client part of
the server install are never making it through - all tests have turned
purple and the log is full of "data flooding from 127.0.0.1, closing
connection".

I even reverted the client directory to the default from the
installer, with no change.

Pointers to how to further diagnose this, or even better resolve it,
appreciated.

Hi

my msgs test is always green, even if there is a warning in the /var/log/messages file

I configured "hobbit-clients" like this:

DEFAULT
        LOG     %.* %(fatal|error)   COLOR=red
        LOG     %.* warning          COLOR=yellow

HOST=s068a300
        LOG     %.* %(fatal|error)   COLOR=red
        LOG     %.* warning          COLOR=yellow


The "client-local" is configured like this:

[s068a300]
log:/var/log/messages:10240
ignore MARK
log:/var/log/user:10240

The two logfiles appear in the messages column, but the line 
.2007/08/17 14:22:54][s068a300:kern.warning] kernel: program nmhs is using a deprecated SCSI ioctl, please convert it to SG_IO

does not trigger the yellow color, even if there is a "warning" string in this line

Also the is a little output problem: if the log contain very long lines some characters where cut off at the _beginning_ of the line.
If I monitor more than one logfile it not very nice to have them all on one page. Is there a possibility to only display lines which trigger a warning or error, so that the page is empty for errorfree logs. Another nice thing would be to put every log into a single subpage under the log summary.

The problem eventually turned out to be the volume of output from the
ps command.  We have java server software on the host in question,
with a *very* long command line - each line totals over 4K characters
- and over 900 processes.  The total output of ps came to some 4
million characters.

By truncating the output of ps at an arbitrary 132 characters that
output was cut to about 140 thousand characters and hobbit was happy
once more :)
