Hello, For 2-3 days my application throws randomly (not always) such exception:
Traceback (most recent call last): File "/usr/lib64/python2.5/site-packages/django/core/handlers/ base.py", line 86, in get_response response = callback(request, *callback_args, **callback_kwargs) File "/home/www/django/czat/ajax.py", line 60, in xml d.delete() File "/usr/lib64/python2.5/site-packages/django/db/models/query.py", line 433, in delete delete_objects(seen_objs) File "/usr/lib64/python2.5/site-packages/django/db/models/query.py", line 982, in delete_objects del_query.delete_batch(pk_list) File "/usr/lib64/python2.5/site-packages/django/db/models/sql/ subqueries.py", line 88, in delete_batch self.do_query(self.model._meta.db_table, where) File "/usr/lib64/python2.5/site-packages/django/db/models/sql/ subqueries.py", line 35, in do_query self.execute_sql(None) File "/usr/lib64/python2.5/site-packages/django/db/models/sql/ query.py", line 1974, in execute_sql cursor.execute(sql, params) TransactionRollbackError: deadlock detected DETAIL: Process 30291 waits for ExclusiveLock on tuple (0,96) of relation 148468 of database 98304; blocked by process 30301.
