lslb - ExtConn timed out while connecting.

[Clockwork]

We've just received the new switch, packet loss seems to be gone, but the "ExtConn timed out while connecting." still occurs sometimes, like 1 time every 5 minutes.

There are also no connection failures to the backend servers anymore. I'll keep track of it in the next few days.

Do you still need the strace?

Maybe you can use persistent connections between LB and backend. It will be faster as well.
I do not need the strace, it is difficult to catch the problem now I think.

it seems the problem is not gone now, they've forgot to put the db server on the 1gbit port at the new switch, so it runs now at 100mbit.

However, it will be changed tomorrow, I'll post here after the problem occurs again.
