I just upgraded a server from 5.1 to 5.5. Our tables are all MyISAM. I
have a python script that inserts rows to a table, in 5.1 it worked
fine. In 5.5 it's failing with 'Lock wait timeout exceeded'. I google
this, and it seems that all the cases of people getting that were with
InnoDB tables
I'm getting a Lock wait timeout exceeded error and I'm not sure why. I've
been trying to read this SHOW ENGINE INNODB STATUS output, but I don't
understand what it's trying to tell me.
Can someone give me a hand here?

Increase your Innodb_buffer_pool_size. It will solve your problem.

SHOW INNODB STATUS and, probably, SHOW PROCESSLIST can give you
some additional information about what's going on. Use:
show variables like

Heikki,
Hmm. That's interesting. So if you do a single command, say
INSERT INTO Table1 (X, Y, Z) VALUES ( A, B, C) ;
You actually need to write (I'm not sure of the exact transactional

BEGIN ; --begin a transaction
, autocommit is on.
