I'm attempting to query the performance counters on each IB device/port and
then reset these counters. To do so I'm using madrpc_init to initialize each
port on every poll. Doing so produces the following warning/panic:
ibwarn: [19949] umad_init: can't read ABI version from
/sys/class/infiniband_mad/abi_version (Too many open files): is ib_umad module
loaded?
ibpanic: [19949] madrpc_init: can't init UMAD library: (Too many open files)
I've verified that libibumad rpms are installed. Only calling madrpc_init at
the front end of my polling only allows me to reset the port that was
initialized last. Does anyone have some insight into how I gather/reset each
port without having to call madrpc_init each time I poll that port?Joel Shibata
