RE: RTEMS Freezing

Hi John
    I'm not sure how IBM arrived at those limits, especially with
Enterprise systems, but I think it's a constraint that can be overridden
by the OS as opposed to one within the application
 
Think its hitting a limit in Aix, have seen TEC etc start misbehaving
when you have over 2000 concurrent connection
 
ulimit -a                                    
time(seconds)        unlimited
file(blocks)         unlimited
data(kbytes)         131072
stack(kbytes)        32768
memory(kbytes)       32768
coredump(blocks)     2097151
nofiles(descriptors) 2000

 
/usr/local/BindView/bvcontrol/AIX/bin/lsof | grep kdsmain | wc -l
    1783

very close to 2000, think it opens a dev file for every socket

It the Installation and Setup manual - we talk about a TEMS being able
to support up to 1500 agents,  I know cases where the actual limit...
based on workload and communications is more like 800-900. A Hub TEMS
can support 10,000 agents. I know many sites that surpass those limits
but they sometimes experience stability issues - crashes/waits etc. 

I suggest you create some new remote TEMSes, reduce the number of agents
to the documented limits - or below - and then re-evaluate.

Hi All 
    RTEMS seems to freeze when the server has over 2000 concurrent
connection, any parameters I can tune under Aix or look at?
