 * Hi,
 * I’m running WordPress on Docker. This has suddenly occurred.
 * I’ve tried `define('WP_ALLOW_REPAIR', true);` which didn’t sort the problem.
 * Logs:
 * Bad magic header in tc log
 * 2024-02-07 22:39:57 0 [ERROR] Crash recovery failed. Either correct the problem(
   if it’s, for example, out of memory error) and restart, or delete tc log and 
   start server with –tc-heuristic-recover={commit|rollback}
 * I have no idea how to go from here.
 * Help please!
 * TIA
 * John
