telnetd consuming a lot of CPU

F. Xavier Maldonado — Mon, 28 Nov 2005 07:37:11 GMT

Hi everyone,
I have an application programmed in Informix 4gl that every user executes when they log into the system via telnet. But when there are peaks of users tring to connect at the same time, all telnetd processes consume a lot of CPU. How can I optimize this situation? any kernel parameter? any help?

PS: My system is a N4000 with 8 CPU's and 6 GB of memory running HP-UX 11.00 OS.

Hi,

Try clearing /etc/utmpx

Shalom,

If the prior solution does not fix it, there are a number of telnet/telnetd patches in the itrc patch database that may resolve this issue.

What is the current Patch state of the system? What quarterly update is installed, and what is the date on the Core OS installation?

OK, utmpx cleaned and it works fine.
So, I have to apply patches for telnetd daemon.
Thnx everybody
