SonicWall NSa 2650 random reboots

We have HA of 2x SW NSa 2650 with HA license as Primary and Secondary.

The primary one is getting random reboots every few hours with the TSR state:

09/30/2024 17:35:34.848Reboot due to task suspension09/30/2024 17:35:34.848Task Trace tWebMain03:
tWebMain03 810ab220 d24c6700 50 STOP 5f5f5f5f d24c36a0 ad0003 0
Stack trace of tWebMain03:
Up: 0 d, 14:0:20

We are running "SonicOS Enhanced 6.5.4.11-97n", because I don't want to upgrade the stack, as I am scared it can reboot during the update procedure. What could this error above mean?

    Update the current firmware, if you are concerned about a reboot during the upgrade, i would suggest to take it out of service, remove the WAN and have the HA, and LAN connected.

    During the upgrade the standby unit is first to upgrade, then once the standby is online, the primary is upgraded.

    it does take some time, a serial connection into the console port is useful to see the progress.
