malloc() of "64" with the following non-sleepable locks held: exclusive sleep mutex inpr = 0 (0xc4444ef0) locked @ /usr/src/sys/netinet/udp_usrreq.c:378 exclusive sleep mutex netisr lock r = 0 (0xc061be80) locked @ /usr/src/sys/net/netisr.c:215 I'm getting those on the console, and it seems that they only happen when users start an nfs transfer to the nfs exported filesystem. The exported filesystem is a vinum raid5 array but I don't know if that has anything to do with the messages. Before I upgraded from 4.8, I used to be able to send at about 8mb/s to the nfs exported raid5. After upgrading to 5.1-CURRENT, the maximum speed has been only 4mb/s. I'm wondering if the messages above have anything to do with the performance drop.
