Appreciate the backtrace.

Does your `ctrl/time.ini` file appear to be corrupted?

Is this reproducible (e.g. still happening)?

As for the crash, some NULL pointers appear in that backtrace that shouldn't be there (e.g. the `key` argument to `iniReadDateTime()` is `0x0`) which suggests either the `scfg_t` (stored in the heap) was corrupted, or the stack got corrupted during these calls to ini_file.c functions while parsing `time.ini`.

Since the scfg_t element that's used for key argument isn't a pointer in the first place (it's an array of char), I can't really imagine how it'd be set to NULL even through corruption. So that kind of points to stack corruption (e.g. in functions within ini_file.c).

Doesn't seem corrupt.

It's not happened since but then again I don't know which event caused it, if any. Let me know if you need any more information out of the core file.

It appears it was the 3rd timed event "last run time" that was trying to be read from the `time.ini` file when this issue happened. That file is only read when the event thread is started during terminal server startup or recycle.

... so my guess is that it's a recycling related issue, so I'd look at the log around the time this occurred for any other warnings or errors from the terminal server.

Not sure if this would explain it:

There was a lot of recycling and a big gap between 16:03:36 and 16:05:07 which, I assume, is when it was doing a core dump.

event thread just has
