GemStone 6.1.5 Time Bomb

Ok, let's see a show of hands - how many people have GemStone projects running on 6.1.5?  Ok, of those, how many encountered a mysterious crash yesterday?

It seems that RcQueue uses a timestamp for its records.  That timestamp is the number of seconds since January 1, 1995.  It's constrained to be a small integer.  Yesterday, it overflowed to a large integer, violated the constraint, and brought our production server to its knees.

Fortunately, there's a fix in GemStone 6.6 - it now records timestamps since January 1, 2005.  There, that fixes the problems.  Everybody set your watches for January 5, 2022.
