I have been using Fedora LXDE for a few months without pay much attention to my home directory until I noticed there was a huge log file called ".xsession-errors" under my home directory. This 25GB file had some seemingly repetitive sections as shown in the end of this email. I guess there might be something wrong and the system just kept adding complaints to this log file which finally clogged my home directory. Can you please help target the problem? Thanks.

The ".xsession-error" file contained something like
