log processing warning

[Mark]

I'm running Urchin 6.5 and almost every day a few log files in
hundreds will report the following error:
...
data lines: 1 (100%)
WARNING: (7044-76-234) Unable to reposition to specified location in
logfile.
...

I've seen this reported in forums and other locations, but I've never
seen any official answer as to what could cause this error and if
there are any workarounds.

In all cases I'm able to open/view the logfile without difficulty, and
I've been unable to find any sort of pattern that might indicate
what's happening. It's frustrating because it looks like it dies on
the first line (data lines: 1) and fails to process the rest of that
log. Because this happens so frequently the Profile Task History
window is littered with 'Warning' statuses which makes it hard to find
real problems I can actually do something about.

Thanks,
Mark
