RE: Can't create mutex semaphore: too many

["Luchini, Kristi L. via Tech-talk" <tech-talk at aps.anl.gov>]

Hello,

 

I have a MVME6100 ioc running RTEMS that appears to be having a resource issue.  Does anyone recognize these error messages below and happen to know function call that I can add to the st.cmd to increase that resource? Do  I need to increase the number file descriptors?

 

If I reboot the ioc the message will go away and the iocs works fine, but after some period of time, a month or so, this message reappears and you can’t access pvs over CA, which I assume is because the iocs seems to be too busy spewing error messages.  

 

Any help would be appreciated.

 

Thanks,

Kristi
