This change happened between 1.6.x and 1.7.x versions.
Basically, one member of the structure was found superfluous
and was deleted.

Personally, I am not a big fan of "log to SHM buffer" feature.
It requires you to use *special programs* to access it.
Your customer was bitten exactly by this problem.

Using good old "log to files" approach is way easier,
and since Linux has ramfs/tmpfs, you don't need real
writable storage to use it.

As to immediate solution - using syslogd and logread
applets from the same version of busybox should work
regardless of SHM buffer format changes.
