cron checks and options table

  • WP 3.2.1, php 5.3.2 mysql 5.1.41 Ubuntu 10.04 LTS.

    wp-cron checks periodically with WordPress about updates. Fine. It leaves an entry name cron in the XX_options table. Fine. This has been working OK on a number of sites that I have on my server.

    But the other day, I got completely locked out of one site – and one only. Eventually after putting debugs and stuff in I noted that the X_options table which usually has a few hundred entries in had only one – the cron entry.

    I have trawled the logs and found no mention of a cron job going awol. Rather silly – I just overwrote the table with another copy and got back into the site so I can’t say exactly when it was that the cron job run but it was as if the whole table was dropped and just the one entry inserted. Literally nothing else.

    Can anyone think of a possible explanation for this? Has anyone else seen it? I would hate it to happen again!
