Hi -
Does anyone have any pointers on what a virtualtransaction of '-1/0' means?
I'm using SSI and an example is
locktype | database | relation | page | tuple | virtualxid | transactionid | classid | objid | objsubid | virtualtransaction | pid | mode | granted | fastpath
----------+----------+----------+---------+-------+------------+---------------+---------+-------+----------+--------------------+-----+------------+---------+----------
page | 16384 | 468238 | 19216 | | | | | | | -1/0 | | SIReadLock | t | f
This is incredibly hard to search for.
I see these for page, tuple and (perhaps a clue?) one relation, and I'm seeing the page and tuple locks accumulate over time. Eventually this results in an "out of shared memory" error.
Any help is appreciated.
Thanks,
Mike
