flush logs taking unusually long and causing locking. (5 replies)

Hi Guys,
Need some help urgently.

mysql version: 5.0.51

My my knowledge, flush logs closes and reopens all log files. In case of binlogs, it creates a new file with incremented sequence. And this process takes no longer than half a sec.

but i am unable to flush the logs from root@localhost either.
while it's in progress, other connections are showing:
"waiting for read lock"


pls help as i must flush the logs during my mysqldump for backups.


Thanks.
