Foldersync Freezes & Crashes Phone (SMB Sync)

[Brant Campbell]

I've been testing FolderSync (Lite) to synchronise an SMB share via WiFi that contains approx. 100K files in 35K folders total of about 20GB.

There are about 300-400 file changes a week.

The phone is a Samsung Galaxy S4 that it not rooted with a 32GB external SD card.

 

After about 3-5 minutes FolderSync appears to freeze. Often after another 5 minutes or so the phone will reboot itself.

FolderSync has never been able to complete a full sync despite trying 30 times or so.

 

Any ideas?

 

Regards,

Brant

I have the same Problem - Nexus 7 with Folder Sync Lite an ~ 30 Folders and 2000 Files (pictures)
Device freezes an then reboot
No Special Folder Structure or Files, just all the folders in one root folder and pictures in every folder

This issue could possibly be fixed in the latest beta release (at least a similar issue was, don't know if its this exact one).

Hello! I have the exact same problem now, a year later! With about 430 files of music. When i watch the sync status, at first it syncs fast, and then slower and slower until it stops and the phone reboots itself.

Me too. Nexus 5, ever since lollipop arrived. Full paid version. Syncs to Google drive and Box. Sometimes causes my alarms not to go off in the morning.

I've the same problem with my Nexus 5 and Lollipop. The phone freeze almost every day. Sometimes after an hour and sometimes after a day, but it rarely ran longer than one day. Most of the time the phone freezed while using google chrome. So I thought is has something to do with chrome. But I also often saw that folder sync uses lot of CPU. So I tried to delete folder sync. The result is, the phone is running since one week without any problem. So for me its clear that folder sync is one, perhaps not the only problem, on my phone.

I'm using owncloud which uses external folders like smb and dropbox. I saw that smb and dropbox are much slower than the "real" owncloud. It cloud be this is the problem?!

It seems there are issues on Nexus 5 (and possible others) if you have enabled md5 checksum on folderpair. Maybe it it has something to do with the new runtime ART.

Anyway, for some people it helps to disable md5 checksum calculation.

MD5 is enabled for all Folder Pairs in my Nexus 5, and I'm not seeing this issue syncing with Microsoft OneDrive.
Android version: 5.0.1 (LRX22C)
Carrier: T-Mobile USA

To be clear, I have a Nexus 5 with checksum enabled, also without problems, but some have reported its helps to disable it when they have experienced similar problems.

hi

i have experienced the same problem with foldersync and nexus 5 lollipop.

Hi all

I can confirm the workaround with disabling md5 checksum! Before this change my Nesus 5 lollipop freezed almost every day and the phone was really sluggish all the time! Since you wrote this, I disabled md5 checksum and everything works fine so far!!!

What I do not understand is, why an app can freeze the whole phone? Normally this is the job of the operating system to kill such an app. Exactly for this, android has the ANR feature, which stops a not responding app after a few seconds. But here, this is not the case.

Thank you for the tip Andreas!

Best regards
