Public bug reported:
Binary package hint: mysql-server-5.0
I'm working on a backup solution for systems that requires running "flush
tables with read lock" followed by an lvm snapshot. In testing, I've had
multiple instances where the flush tables will hang with no particular solution
short of killing mysqld.
The distro currently includes 5.0.22, and lo and behold in the 5.0.23 changelog
fixes:
"A compatibility issue with NPTL (Native POSIX Thread Library) on Linux could
result in a deadlock with FLUSH TABLES WITH READ LOCK under some conditions.
(Bug#20048)"
Can the patch be backported/fixed in 5.0.22 please?
** Affects: mysql-dfsg-5.0 (Ubuntu)
Importance: Undecided
Status: Unconfirmed
