PIX memory error

Hi

Is there any way to see what the following error is and how to stop it,

Message #102 : _tcp_listen: failed to create thread for interface 2 port 23
Message #103 : process_create: out of memory

Thanks Craig

PIX memory error

Craig,

We may need more information than this to find out the root cause. It seems like the Pix was trying to open telnet for either itself or pass through because it was low on memory.

This troubleshooting should be focused on memory. What is the status of it at this point?

PIX memory error

Hi Mike

Thank you for the response, on the interface in question this is a DMZ interface and Telnet should not be on the interface or being sourced from any server.

Please see the following:

PIX memory error

Indeed,

Is this during business hours? Cuz It may increase during heavy traffic. Is this a normal usage of the memory, have you noticed it going up or something? We may be hitting a hardware limitation.
