Hi all,

I get panic "cluster_rbuild: too much memory" on my -current Sparc.

>From kgdb:

 #2  0xf8028df4 in panic (fmt=0x0) at ../../../../kern/subr_prf.c:142
 #3  0xf803ea50 in cluster_rbuild (vp=0xf8669d80, filesize=0xf871394000000006,

     at ../../../../arch/sparc/sparc/trap.c:1143

File kern/vfs_cluster.c:352 is:

  /*
   * No room in the buffer to add another page,
   * terminate the cluster early.
   */
  if (tbp->b_bufsize + size > MAXBSIZE) {	// 61440 + 8192 > 65536
#ifdef DIAGNOSTIC
    if (tbp->b_bufsize != MAXBSIZE)		// 61440 != 65536
      panic("cluster_rbuild: too much memory");
#endif
    brelse(tbp);
    break;
  }

Any ideas?
