out of memory issue

[rajatsaxena]

I am using 128channel UCLA silicon probes to record for ~5hours, and the final output binary file is of the order of 140GB. I am running into memory issues. I have 64GB RAM and 8GB GPU. Here is the error output:

We normally don't have problems with recordings of up to 30 mil spikes and with less RAM. Can you monitor your RAM useage to see where it's going? Are you on a Linux machine?
