eAccelerator for PHP 5.2.4 + Majordomo unsubscribe fix

eAccelerator is being rolled out on the servers for PHP 5.2.4 tonight.  Existing installs of ionCube Loader and Zend Optimizer — where necessary — will still be on the servers.  The spurious deadlocking issues on Borel/Echelon with PHP 4.x and eAccelerator are hopefully limited to PHP 4.x and not script-specific.  Both Echelon and Borel will be monitored to ensure stability.

Majordomo has also had its unsubscribe feature fixed for mailing list members.  Majordomo attempted to change group IDs beyond what it’s entitled to change, thus commands sent to majordomo@<domain> with “unsubscribe <list name>” always failed.
