RPC request error message

Apr 24 06:16:08 windriver kernel: RPC request reserved 240 but used 244
Apr 24 06:17:58 windriver kernel: RPC request reserved 240 but used 244
Apr 24 06:17:58 windriver kernel: RPC request reserved 52 but used 56
Apr 24 06:34:35 windriver kernel: RPC request reserved 240 but used 244
Apr 24 06:34:35 windriver kernel: RPC request reserved 52 but used 56



I get about 50-200 of these messages each day. Kernel is 2.4.18. I see
this message in one of Neil's recent patches.

    +       /* Reset response buffer and release
    +        * the reservation.
    +        * But first, check that enough space was reserved
    +        * for the reply, otherwise we have a bug!*/
    +       
    +       if ((rqstp->rq_resbuf.len<2) >  rqstp->rq_reserved)
    +               printk(KERN_ERR "RPC request reserved %d but used
%d\n",
    +                      rqstp->rq_reserved,
    +                      rqstp->rq_resbuf.len<2);
    + 
    
Is anyone else seeing this?

Shouldn't be in 2.4.18.  They should only be in -ac patches.
I'm fairly sure that the latest -ac gets all the numbers right.

Exactly what kernel are you running?
