Has anyone come across the following error:
%KERNEL-1-CREATEPROCESSFAILED:Error in creating process: Unavailable free stack; stack type: 1; Name: LinkUpdPrcs
Any ideas what is the cause.
Thanks.

Explanation: This message indicates that the create process has failed; the system
is out of processes. The Catalyst operating system allows a limited number of processes
based on the number of stacks available. When stacks are unavailable, this message
is generated. The first [chars] is the process ID, the [dec] is the stack type,
and the second [chars] is the process name.
Recommended Action: Issue the show users command to check how many telnet sessions
have opened for the switch. CatOS switch allows only a limited number of processes
with a type 2 stack (for example, Console, snmpdm, VtpRx, THREAD, telnet145) in
the system. The maximum number of processes with a type 2 stack is 13. To view
the type 2 stack processes issue the show proc command. These processes will
have the value 'xxxx/12288' under the 'Stacks' column. Telnet is one of the processes
which require a type 2 stack. When all type 2 stacks are used, any attempt to connect
through telnet will result in this error message. Disconnect the telnet sessions
opened by the remote device using the command disconnect {ip_address}. Also investigate
why so many connections are opened for the switch from the remote device.
hope this help.

to put it simly, you may have too many telnet connection to the switch and have exceeded allowed connection.
show user to confirm how many telnet are used. Otherwise, it might the other processes but most likely it's the telnet.
If you limit the number of users that are allowed to telnet to the switch, then you shouldn't see these messages.

Hello,
This will require a login on CISCO but if you have one, good place to check:
