[ULTRAMONKEY-USERS] Ldirectord trouble about monitoring service port

[Hideaki Kondo]

Hello, Simon-san, UltraMonkey-Users,

Thank you for your continued support.

# I'm sorry for my poor English in advance.

I've found a trouble of ldirectord about monitoring
service port of realserver.
Ldirectord seems to exit when ldirectord detects
the service port (80(http), 21(ftp), etc) is down.

The cause of this trouble is the lack of SIGALRM
cancellation (alarm 0;) as follows.

I think that the following trouble is similar to this one.

In this connection, it seems that this bug fix is reflected
in heartbeat-1.2.5.

Would you please update heartbeat-1.2.3.cvs.20050927-1.rh.el.um.3.xxx
for this bug fix ?
# I think that early update is better because this function (
# check_connect()) is often used.


Best regards
