Hello,
Today I have see that the Sync application (2.3.3) from my synology (2413+) don't start anymore. Try many time to relauch it but without succes... I have 2 other NAS and no problem with them. I have updated today to 2.3.4 but the problem remain.
I put in zip the last files found from var and bin, no found dump files. https://drive.google.com/file/d/0B0y249aOtdK1ZHpHVVVNU3h3bnc/view?usp=sharing
Hope to find a solution
