Description:
Hello,

I am trying to determine if my problems is a bug in mysql 4.1.12 64bit. 

I have a Master DB and 3 slaves. 
All the slaves have different server_id in my.cnf. 

I just dropped all the Slaves and refreshed with new copies via IBhotbackup from the Master (A).

Started up the slaves. 

2 (B&C) of the slaves are on a local private network next to the master.  -- 64bit
1 (D) is remote sitting at my desk.   -- 32bit 

The 2 local slaves can not keep up. They slowly fall back currently both approx 45067 back. 

The little 32bit version I have can keep up or close the gap after sql errors where the 2 64bit never can.

For example: 

Server (D) had an error overnight that i repaired when I got in. 
IT was 
Seconds_Behind_Master: 60924 
Now Seconds_Behind_Master: 59251 and closing. 

Servers B & C 
This morning 
B-- Seconds_Behind_Master: 43378
C --Seconds_Behind_Master: 43963

NOW 
B-- Seconds_Behind_Master: 45098
C --Seconds_Behind_Master: 44804

As you can see they are going the wrong direction. 
Any ideas on where else to troubleshoot this?

How to repeat:
Good question. 

Start slave for now  :)

Thank you for a problem report. What Linux is used on that problematic slaves? If it is Debian, please, send the glibc version used.

Please, in any case, try to repeat with a newer version, 4.1.19.

It is Red Hat Ent. 

I have just updated the 4.1.19 on slave with no new results.
I am going to upgrade the master as well.

Please, upgrade master and inform about the results. We'll have to check on the latest version anyway.
