Hello people. Greetings.
I have reported this issue more than once on GitHub. I also think it’s good to ask people here if any one has these issues.
Sometimes the entire system will freeze completely blocking all transactions. A look at htop in th terminal may show almost no activity on the processors. It will appear th mysql just went away. This has been observed on 2 installations, one is a fresh v9, 2 months old, another is an upgrade. Its actually much worse with the fresh installation. The entire server must be restarted, nothing else works.
2n observation; the pos may freeze intermittently while the cashier is scanning items, on responding; the sale is automatically submitted with the items scanned so far. Somehow, something in the code just submits the invoice; skipping the pay/tender and submit confirmation popup windows. CRITICAL. This occurs about 10 to 20 times daily; out of over 900 invoices. This may appear a little but we all know even one occurence of such can reduce the perceived reliability of the system.
- Some sales automaticaly post twice. I shared with shot on github, less than a second between 2 invoices, same user, same item, serially entered.
Since there were no responses from devs o guthub, I don’t know if you patches were made for these in v10; but we’ll upgrade on Sunday.
If any one ha encountered and overcome any of these; please enlighten.
I am attaching a screenshot of what the staff got from f12 when it froze.
