[-- Attachment #1 --] I'm getting weird problems on my 5.0 system trying to lock access to files on an NFS volume (RedHat NFS server). For example, here is what happens when I try and vi a file on the NFS volume: 58532 vi CALL flock(0x3,0x6) 58532 vi NAMI "/var/run/lock" 58532 vi RET flock -1 errno 4 Interrupted system call 58532 vi PSIG SIGINT caught handler=0x804b340 mask=0x0 code=0x0 58532 vi CALL sigreturn(0xbfbfef58) 58532 vi RET sigreturn JUSTRETURN Note flock is being called with LOCK_NB|LOCK_EX, i.e. non-blocking; yet it blocks until I SIGINT it. I am running rpc.lockd on the client, and it appears to also be running on the server (I don't know if Redhat includes a working lock manager or if it fakes it like ours used to). Any ideas?
