Large files cause jsDAV to hard shutdown

[ooxi]

Is this reproduceable? Does it depend on the file contents? Is 2 GB the exact border when this starts happening? How much RAM do you have?

[briangonzalez]

Yes, reproducible in that it happens every upload. of a "large" file. I am not sure about the file's contents, but I have mostly been testing with .zip files.

I has jsDAV running on a an RPi with 512MB of memory.

I am going to test files of the following sizes generated using the shell command: dd if=/dev/zero of=output_400MB.dat bs=1024 count=400240. Not that these are all .dat files.

Files

• 400MB (just under memory cap) - SUCCESS
• 600MB (just over memory cap.) - SUCCESS
• 750MB - SUCCESS
• 850MB - FAIL
• 1GB - FAIL
• 1.5GB - FAIL

Tailed the syslog, and look what I've found:

[briangonzalez]

@ooxi Any idea what could be going on here?

[mikedeboer]

@briangonzalez how are you uploading files? Through a browser POST form or using a file manager with PUT?

[mikedeboer]

Oh, and also an important question: which version of jsDAV are you using?

[briangonzalez]

I am using a clone of master at 558377a.

Also, I am using Transmit and Cyberduck on the Mac, both of which have the same issue.

[mikedeboer]

Ugh, I have so little time :( I will take a look at this, because it's something a NodeJS lib should do well!

[briangonzalez]

No worries, take your time.
