060810 14:46:45 [ERROR] Slave: Error 'Can't find record in 'group_upload_counter'' on query. Default database: 'db1'. Query: 'insert into group_counter (...) values('username', now(), 1, now())', Error_code: 1032I invoked "perror 1032" to see what the error was all about but got the following message:
-bash-3.00$ perror 1032
Illegal error code: 1032
I asked on the #mysql and Jay and Roland were quick to respond. We all researched for some time but the only thing we were leading to was something about running out of disk space which wasn't the issue in this case. So I decided to check the table for corruption and guess what, the table was indeed corrupt and was fixed with a simple REPAIR TABLE invocation. After that I started the slave and it caught up fully.
