There is a memory leak in 7.24 scheduled scripts (/system/script and /system/scheduler) - looks like all the script output (everything it outputs to its "invisible console") gets buffered in memory in RouterOS 7.24 and 7.24.1.
If you have scheduled/long-running scripts that do a lots of output and experience strange crashes, reboots or high memory usage in RouterOS 7.24/7.24.1, this might be the cause.
This has been reported to MikroTik (SUP-222576).
