I have a server which has been running for about a year now. It

server is
a Compaq server with dual Pentium II (Deschutes) 400MHz 512Kb cache
CPUs, 320Mb RAM and SCSI drives. The OS is Gentoo Linux.
From the beginning it has behaved strangely - connections to mysql
(be
that with the mysql textclient or from PHP) fails about 2 out of 3
times
in periods. Some times there are no problems, other times it's
almost
impossible to connect. This behavior has been consistent from the
start,
so it has been a problem when running both mysql 3.x and 4.0.x.
I have monitored the servers load and the loads are the same in the
periods when it fails as in the periods when it doesn't. I have
tried
monitoring the mysql logs, but no entries show up upon the failed
connection attempts.
No other services malfunctions in this way, or indeed at all on the
server.
I have run out of ideas on how to debug this problem, can anybody
here
help me?
What error did you receive?
In PHP it just says connection failed. I can't remember the exact
message the textclient gave, and it is in a period of not failing right
now (typical!) so I can't get the message right now. I think it gave a
message about connection aborted. As soon as it does it again I'll write
the correct message to the list.
