That doesn't look right to me. Why would you run 4000+ instances of the amqsputc sample program?
Personally speaking I would first of all send them down to hell and see whether or not runmqsc works again.
I would try to figure out who is starting all this amqsputc processes.

Hmm...
Maybe you are running out of fork processes or something. |

The error means that HPUX has run out of semaphores. The number is controlled by some tuning parameter which I do not know. However, the real problem is that your client apps are not ending with MQDISC. I suggest you set TCP KeepAlive on your HPUX system to clean up idle client connections.
Here is how you do it on HPUX:
get:
ndd -get /dev/tcp tcp_keepalive_interval
set:
ndd -set /dev/tcp tcp_keepalive_interval 60000
The interval is in milliseconds, so the example sets it to 60 seconds.
The parameter takes effect immediately. If the machine is rebooted the parameter is reset to the default value.
To make the change permanent, add the ndd command to the /etc/rc.config.d/nddconf script. |

thanks!
I had done many setting:
Set mqs.ini
TCP:
KeepAlive=Yes
ndd :
hnmq-G-/var/mqm> ndd /dev/tcp
name to get/set ? tcp_keepalive_interval
value ?
length ?
60000
name to get/set ?
above setting can not fix up the error! '
Now I restart the MQseries after set tcp_keepalive_interval value 15000. |
