I'm running MySQL 3.23.49. Everything was going good until today. I did a couple of large table reads/inserts/deletes on the InnoDB tables which appeared to go fine. I then restarted MySQL which also appeared to go fine. From that point on, however, I kept losing connection with the DB, and couldn't run any queries. A check of the error log reveals the following:
---start err log--- 020521 21:54:13 mysqld restarted 020521 21:54:19 InnoDB: Database was not shut down normally. InnoDB: Starting recovery from log files... InnoDB: Starting log scan based on checkpoint at InnoDB: log sequence number 0 2556753944 020521 21:54:19 InnoDB: Flushing modified pages from the buffer pool... 020521 21:54:19 InnoDB: Started /usr/local/mysql/libexec/mysqld: ready for connections InnoDB: Assertion failure in thread 508094464 in file btr0btr.c line 574 InnoDB: We intentionally generate a memory trap. InnoDB: Send a detailed bug report to [EMAIL PROTECTED] mysqld got signal 11; This could be because you hit a bug. It is also possible that this binary or one of the libraries it was linked agaist 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=268431360 record_buffer=131072 sort_buffer=524280 max_used_connections=0 max_connections=400 threads_connected=0 It is possible that mysqld could use up to key_buffer_size + (record_buffer + sort_buffer)*max_connections = 518136 K bytes of memory Hope that's ok, if not, decrease some variables in the equation ---end err log--- I tried grabbing the latest source and recompiling the database, but still no go. Unfortunately I don't have a backup of the InnoDB tables, so there isn't a whole lot that I can do in that respect. The data appears to still be in the tables, because I can on occasion do a select and it will return data before the database dies. Anyone have any experience with this sort of problem? Thanks.
