Thanks for the data point.
Hmmm... looks as if the likely sequence of events was: create embedded fdtable extend fdtable, allocate external data to handle fd = 524 try to extend fdtable again, crash.
Seems as if alloc_fdtable() or copy_fdtable() are to blame, but the code logic seems to be identical. Hmmmm. -- Vadim Lobanov
