Dear Suppor Team,

I currently have an application running on ESP32-S3 mini, it has 7 tasks and 3 gpio pin interrupts. After running for long time (last test it ran for 20 hours), the following error occured:

Guru Meditation Error: Core 0 panic'ed (StoreProhibited). Exception was unhandled.

What exactly timer_process_alarm is related to? I do not have any timer interrupts on the code. In addition, the log dump always seen to be currupted for this specific error. Is there anyway I can fix it in order to provide some more useful information? I am also attaching my sdkconfig file for reference.

Any assistance and help in order to understand this issue would be greatly appreciated.

Thank you very much,

Rodrigo
