Hello.
If the value of Read_Master_Log_Pos has a normal value, and slave
asked weird position, this could be some internal bug. Now I see
only a single way, but it could be difficult: if you have
--log-slave-updates, use slave binary logs to find the last executed
statement and it's position in master logs, and CHANGE MASTER to that
position.

Hi list,
This night my slave stopped replicating the master (I am using 4.1.11 to
replicate 4.1.9). Whenever I say start slave, The error log of the
slave says:
050430 10:27:12 [Note] Slave I/O thread: connected to master
'[EMAIL PROTECTED]:3306', replication started in log
'www-bin.03' at position 429178917
050430 10:27:12 [ERROR] Error reading packet from server: Client
requested master to start replication from impossible position
(server_errno=1236)
050430 10:27:12 [ERROR] Got fatal error 1236: 'Client requested master
to start replication from impossible position' from master when reading
data from binary log
050430 10:27:12 [ERROR] Slave I/O thread exiting, read up to log
'www-bin.03', position 429178917
The interesting thing is that for the master:
-rw-rw 1 mysql mysql 1073741913 Apr 26 21:52 www-bin.01
-rw-rw 1 mysql mysql 1073742497 Apr 29 01:37 www-bin.02
-rw-rw 1 mysql mysql 429153165 Apr 29 20:20 www-bin.03
-rw-rw 1 mysql mysql 169507064 Apr 30 11:01 www-bin.04
Looks like the master really has no position 429178917 as the length
of www-bin.03 is smaller, 429153165 (if I understand this correctly).
Is there a way to restart replication other than copying everything from
the slave to the master again??
Thanks,
- Csongor
