I have a Synology DS224+ NAS running DSM 7.3.2-86009 Update 3 that has been crashing repeatedly over the past month. The unit (which is less than a year old, with brand new Synology drives) runs 24/7 in my empty house while I'm long-term away in another country, making physical access difficult and requiring me to call in a favor for a power cycle each time it goes down.

The crashes leave no useful evidence -- the DSM Log Center shows nothing around the crash times, /var/log/messages has no entries for the crash periods (the log simply stops and resumes after the reboot), and dmesg shows only benign SATA negotiation errors on the reboots. S.M.A.R.T. tests on both drives come back healthy. When my friend visited to power cycle the unit, all front LEDs were green, so apparently the NAS thought it was running normally but was completely unreachable on the network (EHOSTUNREACH). Active Insight shows the device going offline but has no pre-failure metrics or warnings to offer.

As I write this, the NAS is down for the 3rd time in the space of a month. Before this latest event, I had set up a weekly scheduled reboot via Task Scheduler as a possible mitigation, which has run successfully for 2 or 3 weeks, but this latest crash happened the day before it was scheduled to reboot. I'm also thinking about adding a smart plug for remote power cycling since it's a real hassle for my friend to have to go fix this for me.

The NAS is used primarily for file shares and Hyper Backup to Backblaze B2. I also have a DS124 on the same network that the 224+ also backs up to, which has never once crashed. Has anyone experienced similar unexplained hard crashes on a DS224+ or other recent Synology models, particularly where the unit appears healthy from the outside but is completely unresponsive on the network? Any advice or thoughts on what I can do to monitor or prevent these crashes?

(Also, I ran a DS214 (I think that was the model) for 6-8 years and never had these kinds of issues. I only upgraded to the 224+ because I felt like my original unit was getting a little long in the tooth.)

TLDR: Newish DS224+ halting mysteriously with no information about what's causing the crashes. I'm long-term remote from the unit, so I have to have a friend go reboot it when it happens. Frustrated.

Finally caught a ride on Luas tram 5037 today. I was in the last car which must not have been damaged, because it felt pretty 'original.' Frayed baffle between cars, chipped paint on the handholds, dirty floors, etc. Anyway, it was a smooth ride. Welcome back 5037.

Daughter & fam are visiting in July, and they are vegan+gluten-free. Believe me, I know that's a tough combo to find... anyone have any recommendations or guidance for restaurants around Dublin that can work? Also looking for a Vegan/GF bakery since the grandchild will be having her 2nd birthday here. Thanks in advance!

EDIT: Thank you all so much for these recommendations!! We'll check them out and I'm sure now we'll be able to show the kids a good time food-wise.
