In a Solaris 2.5.4, i have the folowing message in the file '/var/adm/messages':

"WARNING: msgmap: rmap overflow, lost [372,373]"

Q: 1. What is the meaning of this message?
     2. Does this message affect the message queue system?

Thanks,

The 'msgsnd' system call failed; Some processes on your
system are either sending an outrageous number of messages
to each other or they're sending huge messages to each other.

If the load on your system is high and the receiver did not
yet extract enough messages from a queue, the queue
overflows and the result can be found in your message
log ... There's not much yoiu can do; check out which
processes are babbling all the time and try to renice the
sender a bit ...

kind regards,

Jos,
Thanks for the information.

Do you have idea of the numbers in the end of the message?

After this message my system don't work properly with message queues. Does this overflow affects the ipcs system?

Thanks,

Luizk
