Gen 7 Units Uncommand Restart Cycle
We recently observed this behavior on two TZ370 units:
- Ran fine for days (no interruptions, restarts, or other issues)
- All of the sudden one unit started restarting endlessly (into normal mode for about 15 seconds and then restarting)
- The second unit would just restart into safe mode
Since both were running the latest sw_tz_370w_eng.7.0.1-5030-R2007.bin.sig firmware, we ended up having to engage SonicWall and one of the techs initially didn't want to provide a hotfix given how many "hotfixes for restarts there are for Gen 7 units" but fortunately one them provided a hotfix that listed a DPI engine crash issue.
Fortunately we were able to get the firmware hotfix uploaded and restored settings from backups but it was aggravating to see these Gen 7 units react this way.
Nitpick but MS on ping to these units in safe mode is < 1ms but in production with little to no activity it runs around 1-8 ms.
