Hello, I'm (again) encountering a bug with PVFS (2.8.2): I use it with TCP on 16 nodes, an MPI application is running on 38 other nodes and periodically output some data using MPI-IO. The monitoring system of my PVFS nodes shows that the memory cached increases at each write, until reaching 8GB (out of 24GB available on the nodes). At this point the servers stop answering to write requests, the application blocs in IO and eventually timeout. I tried with IP over IB and with Ethernet, both show the same behavior. Any idea where it comes from?
Thank you, Matthieu -- Matthieu Dorier ENS Cachan, Brittany (Computer Science dpt.) IRISA Rennes, Office E324 http://perso.eleves.bretagne.ens-cachan.fr/~mdori307/wiki/
