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 Message from RTEMS ioc: Can't create mutex semaphore: too many Can't create mutex semaphore: too many Can't create mutex semaphore: too many Can't create mutex semaphore: too many Cexp@ioc-in10-mp01> Cexp@ioc-in10-mp01>Error on UDP RX 172.27.72.43:47591 -> 172.27.75.255:5076 at 46 : Can't create mutex semaphore: too many epicsMutex::mutexCreateFailed() 0x00 ca024000 27000000 d5b37962 00000000 ..@.
