[HPDD-discuss] Crash of evicted Lustre client

Dear All, I've seen several cases of crashed client machines lately. There's a high load on the lustre servers and the clients seem to run into time-outs and get evicted. My clients run Lustre 1.8.9 and the servers have 2.1.3, 1.8.7, 1.8.8. Is there a known bug in the 1.8.9 client that could cause this? Regards, Götz Waschk
