Yesterday my production server started displaying the following error message across all sites and sub-sites:
Error
Web Part Error: One of the properties of the Web Part
has an incorrect format. Windows SharePoint Services
cannot deserialize the Web Part. Check the format of the
properties and try again.
Looking in the event viewer I see a nice little message informing me that I am out of disk space on my server.
Source: Windows SharePoint Services
Category: Web Parts
Event ID: 6635
Description:
There is not enough disk space.
Strangely enough today I see the same error on my new 64-bit Dev box. Apparently log files had pretty much filled up the new dev box. There was actually a log file that was 1.5 GB from yesterday. Once I cleaned out the log files and old compressed files on both servers everything returned to "normal"

Is there a way to point the log files to someplace else. I am experiencing the same problem. In less than a week my log files are totaling to 27GBs. Or better yet how can I read them to understand why just recently they are so huge.
Thanks
Reading the log files is one thing. I wish MS would do a better job of giving us log files that don’t require an application of some sort to read through. You could use log parser or something similar to pull the info you’re looking for out but I don’t know how well that would work.
As for moving them it all depends on which log files you’re looking to move. If it’s the log files for the trace logs and usage analysis processing you can move those from the Operations > Logging and Reporting section of Central Admin. If you’re talking about database log files that becomes a whole different story and isn’t as simple as changing where the log files reside.
