I'm experiencing some issue with my "SG500X-24 24-Port Gigabit with 4-Port 10-Gigabit Stackable Managed Switch", especially the 10Gb part.
The 10Gb ports switch links are randomly dropping connection, then bringing back, then dropped again, those in a few seconds. This is making my configuration unusuable.
I'm running a few Linux High Availabilty servers that need to have this link not being dropped (I've tried setted up bonding, with a Gigabit port to ensure service can continue working, but because I'm running DRBD, it's making me a split brain).
Here is the output coming from Linux. Please note that the link is being dropped exactly at the same time on all servers which have been connected to the 10Gb ports (with optic fiber) :

enp12s0 is the 10Gb card, the enp2s0 is the gigabit card. Please note that the link on Gigabit card isn't dropped at the same time.
I'm quite sure it's only related with the 10Gb switch part.
I've tried updating the firmware, maybe it's better, but I'm still having the issue.
Current version/setup
Firmware Version (Active Image): 1.4.1.3 Boot Version: 1.4.0.02
Based on the uptime, I just figured out that my switch seems to be rebooting while I'm having this issue (uptime resetted to 0), but the gigabit link doesn't go down ... so an half reboot ? Only the 10Gb link are doing down.
If I manually reboot it, I can see the gigabit link going down...
