unauthenticated user in login status : zombie Threads

[Armand Krijgsman]

Hi All,

I am new to this forum, so thank you for your time reading my first post.
Since 2 days I keep getting "Maximum connection limit reached" errors, so I went looking in the process list, and found lots of connections to my server from other hosts then localhost.

These threads seemed to be inactive, so I killed them.
They however keep the connection reserved in the proccess list, even when their status is killed.

I was happy to be able to create a replication server back 2 years ago (which is still working) So I am a bit affraid in doing a full mysqld restart. (so don't even know if this empties up the connections)

My questions:
- Is there a way to flush the threads? (mysqladmin flush-threads isn't working)
- Is there a way to block outside tcp connections without blocking the replication host?
- Is it save to restart mysqld for my replication host? (And will this clear my threads list?)

Thanks in advance!

Regards,
Armand
