I forgot to point out that this is InnoDB
I've searched Google and found the following disquiteing thing: http://www.innodb.com/oldbugs.html:
"Closed or old bug reports: Almost all of these bugs have been fixed. There are
some old bug reports where the cause of the bug was never found, but because
there have been no bug reports for newer versions of InnoDB, these reports are
not considered actual any more. "

August 13, 2001:
The fsync problem which was fixed in 3.23.40b and .41 could cause the
following warning message on some Unix flavors:
Innobase: Warning: difficult to find free blocks from Innobase: the buffer pool! Consider increasing the Innobase: buffer pool size.
If you encounter the above message, upgrade to 3.23.41."
However, I'm already using a newer vresion than that:
ccs012:~ # rpm -qa |grep mysql mysql-shared-3.23.44-5 mysql-Max-3.23.44-5 mysql-devel-3.23.44-5 mysql-navigator-1.2.3-106 mysql-client-3.23.44-5 mysql-3.23.44-5 mysql-bench-3.23.44-5 ccs012:~ #
This is a mission critical DB. Am I the lucky un-fortunate to re-dicover this
supposedly fixed bug?
