mysqld service crashes on restart, after importing mysqldump #innodb
- by ubunut
I have 2 mysql servers. Let's call them server01 & server02. Both have the same configuration: mysqladmin Ver 8.42 Distrib 5.1.61, for redhat-linux-gnu on x86_64

I make a mysqldump on server01: mysqldump -uuser -ppassword --all-databases testservers.sql
(most tables in these databases are innodb, some of the mysql.* tables are Innodb too)
Then I import the testservers.sql on server02: mysql -uuser < testservers.sql
(mysqld has been started with --skip-network).
So far so good, I can login into mysql & everything seems to be ok. BUT when I exit to the shell and execute service mysqld restart, The service fails to start.
stack-trace in /var/log/mysqld.log:

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.
key_buffer_size=8384512
read_buffer_size=131072
max_used_connections=0
max_threads=151
thread_count=0
connection_count=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 338324 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...

A typical mysqdump entry looks like this:
DROP TABLE IF EXISTS `adodb_logsql`;
/*!40101 SET @saved_cs_client = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `adodb_logsql` (
`id` bigint(10) unsigned NOT NULL AUTO_INCREMENT,
`created` datetime NOT NULL,
`sql0` varchar(250) NOT NULL DEFAULT '',
`sql1` text,
`params` text,
`tracer` text,
`timer` decimal(16,6) NOT NULL DEFAULT '0.000000',
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='to save some logs from ADOdb';
/*!40101 SET character_set_client = @saved_cs_client */;
IF I change all occurrences of "ENGINE=InnoDB" to "ENGINE=MyISAM" before import, then the service has no problem restarting. I'm quite puzzled as to what's happening, maybe I'm just an idiot, then by all means tell me so.
Any help would be greatly appreciated!
