The gui shows me a warning with the category ERROR: SQL Command Failed, see log
However, when I check the logs I can only find:
2012-04-21 16:15:12,209::ERROR::[database:90] SQL Command Failed, see log
The entry before that is:
2012-04-21 16:13:57,740::ERROR::[downloader:526] Failed login for server newsreader1.eweka.*:119
Only thing I can add is that disks were under heavy load at this perticular time.
