mb_map full   
Hi, I really appreciate any help on this, I receveid the message on the subject and no one on the network can access QNX
 . I have to reset the server to get acces again. This is happening many times during the day and with some of my 
costumers who have qnx4. This begins to happen a few days ago. Thank you for any help.

Re: mb_map full   
Hi Victor,

What TCP stack do you use? I'm assuming Tcpip 5.10. Try to increase the number of memory pools in first argument of -m 
option of Tcpip. Default value for this option is 64,65535.

Respectfully,
Oleg

Re: mb_map full   
Oleg I am viewing weird entries on Ps -A like this:
1432  1432  27 10o REPLY    21   20K login -h bd07c44d.virtua.com.br -p
854   854  16 10o REPLY    21   20K login -h static.vnpt.vn -p
2435  2435  32 10o REPLY    19   20K login -h 95.9.191.5.static.ttnet.com.tr -p
2521  2521  34 10o REPLY    19   20K login -h 55-140-164-181.fibertel.com.ar -p
 I guess this is related with the problem, like non autorized entries to qnx4 or a qnx4 virus ? Is it possible ? How can
 I block theese entries ?
I really appreciate the help.

Re: mb_map full   
Victor, do your system connect to network? What services did you run?

Respectfully,

Hi Victor,

Sorry for delay with my answer.

This should be a login command that is launched from telnetd to establish remote connection. Is it possible that your 
QNX system has many telnet connections at one time?

Oleg

Re: mb_map full   
Hi Oleg, thank you for your help. I search on internet and I found that there is a virus which is attacking telnet port 
23 sending a lots of logins to crash the service. So, I changed the telnet port on Qnx, and I hope that that fix the 
problem. >Thanks again...
Victor.
