Upload Issues - File Size

[Jamburlington]

Hi,

We are having a number of issues uploading files to the server.
In this instance, *.OME files > 420MB fail to upload.
The initial error was a javaheapspace error. This was rectified by creating a vmoptions file and allocating more memory up tp 1500MB. We now get the following error
java.lang.RuntimeException: java.lang.OutOfMemoryError

We are running OMERO 4.1 on an x64 bit machine. The importer however seems to be using 32 bit. Is there a way to change this?

We have successfully uploaded TIF stacks up to 2GB. Files larger than 2GB also fail?

Cheers,

James

Hi James,

I've seen the errors on our QA system. Would it be possible to get our hands on at least one of these files?

The importer will use whatever Java virtual machine you have configured. If this is 32-bit, then it's 32-bit. You may need to install the Java JDK in order to get a 64-bit virtual machine on your platform.

We regularly import files > 2GB on 32-bit and 64-bit platforms. The only restriction is that a single 2D, X-Y plane must currently be smaller than 64MB. You can remove this restriction but it requires some configuration.
