I can't put my finger on exactly when this condition started happening. Sometime in the last two weeks or so. When I click deploy, about 75% of the time, the first try fails and I have to click deploy again. I experience this condition when i try to deploy both Full and Modified flows. When the first attempt fails, sudo journalctl -f -n 25 -o cat shows nothing related to Node-RED. Node-RED v0.19.4 Ubuntu 16.04.6 LTS Release: 16.04 Codename:xenial

That error is coming from some extension you have installed in the browser. It is not node-red.

Thanks for the quick response! I didn't think to look in the browser console. I only have two extensions: 1Password and Cisco Webex. Both are now disabled and it seems to have made a difference.

[image] athome: Cisco Webex I would look to that being the culprit initially. Depending on what version you are using. I always keep it turned off and only turn in on when I have to use the c**ppy service from CISCO. I use the "SimpleExtManage" Chrome extension to be able to turn on/off extensions quickly.

This week's sprint is going to be dedicated to resolving this condition, which still persists. However, I am certain that I don't know where to start in the diagnosis. I have read a few posts to which some of you have contributed related to JavaScript heap out of memory and they are pretty CSI-like in their forensics. I have validated that I can cause a JavaScript heap out of memory condition when I hit Deploy. See example log data below, which was created when I tried to deploy a change using Safari. I usually use Firefox, so I don't think that this is browser-dependent. I have removed all browser extensions from Firefox. There is also some kind of time element. After an initial failure, or two, I can usually deploy changes without incident as long as I don't wait too long between deployments. If I wait for something that feels likt 15 or 20 minutes, the heap error will occur. For the first time, I have received this message this morning: 6/17/2019, 7:06:22 AMmsg : string[27] "Existing flow file is empty" 6/17/2019, 7:06:23 AM msg : string[122] "Restoring flow file backup : /home/homemanadmin/.node-red/projects/nodered-homeassistant/.flows_homeMan-server.json.backup" From time-to-time, this condition will occur when I access my node-red instance from my browser (i.e. http://192.168.14.178:1880) for the first time at the beginning of the day.

Is it possible that having too many sequences and/or too many nodes in a flow could cause the JavaScript heap overflow? My irrigation flow is my largest. I have disabled this flow to test to see if it makes a difference. I have posted it here. Well, maybe not. The flow export is 185K characters and the post limit is 32K.

My irrigation flow had 277 nodes. I have just made a change that resulted in a reduction by 55. This change has made a dramatic improvement in the behavior. I have been able to Deploy without incident after making this change.

For reference, my live flow file is 626k (1025 nodes). -rw-r--r-- 1 pi pi 626K Jun 15 13:19 flows.json Oddly, my secondary instance isn't much smaller though it has a lot less in it - 409k (655 nodes). I have no problems with either.

TotallyInformation, Thanks for the reference. The numbers i quoted above (185k and 277 nodes) were for the contents of a single flow tab. My flows file is 851,289. How did you count the nodes across all tabs? That would be useful to know how to do.
