AppDB problem

[Segin]

While changing user prefences, I got this error:

Database Error!
Query: REPLACE session_list VALUES ('0b7b7e6e2b25056088b212db53619c9c', 
'', '', 
'current|O:4:\"user\":7:{s:7:\"iUserId\";s:5:\"72211\";s:6:\"sEmail\";s:17:\"segin11(a)yahoo.com\";s:9:\"sRealname\";s:0:\"\";s:6:\"sStamp\";s:14:\"20051229230938\";s:12:\"sDateCreated\";s:19:\"2005-07-09

'', NOW())
Deadlock found when trying to get lock; Try restarting transaction

Just thought this was worth reporting.
