Dear all,

Recently one of our servers randomly stop responding, but it does not =
hang.

When the problem happens, all the network services stop responding, but
the server is still running. Then many processes are queued up and cause =
the=20
avg no. of process running sky to over 100 in 10min! If I was connecting =
an=20
ssh to the server, it just stop response but the connection is still =
there.
ping also has response.

The most strange thing is, when I press an ENTER key at the console, the
problem solved instantly and everything back to normal. Even my ssh =
connection
will have response again.

Our server's config:

Hardware: Dual P3-700Mhz, 640M RAM, 2 x 10G IDE HDD running Software =
RAID-1
OS: RedHat Linux 8.0
kernel: kernel-2.4.18-14smp

Special config:
- freeswan-1.99_x509_0.9.15_2.4.18_14 installed

Do you know what happens and kindly give me any suggestions? Thanks!


Best Regards,
Charles
