Hi,
The server is Redhat 5 32bit.
It is not easy to produce the problem so I will just write the experienced problems not how it is produced.
1) During login, it shows the last login time and then waits for 3-4 seconds to give shell prompt (considerable)
2) Sometimes the connection window freezes (console is also) not showing any characters pressed; after 4-5 seconds it shows all the characters written. (considerable)
3) Almost every half an hour, while pinging the server it shows Request Timeout then the NFS share drops.
4) CPU is seen as 99 %idle in sar output for the normal times. When the freeze happens the sar output shows 0 %idle, 70 %iowait and 30 %system.
Then the screen freeze and connection drops.
Any recommendation to check where the problem might be? Any ideas?
